Philosophy - Philip Stokes
INTRODUCTION
Is there any meaning to life? Does the universe have a purpose? What really exists, and what does ‘exist’ mean? What is ‘mind’, and how does it relate to ‘matter’? What do we know? Do we in fact know anything at all, or is everything we think we know just hypothesis? Do human beings have free will, or is everything we do determined by prior causes and circumstances? Are ‘right’ and ‘wrong’ just matters of opinion? It is questions such as these that philosophy seeks to answer.
And if some of these questions seem somewhat removed from the realities of everyday life, then how about these? Is it ever right to go to war? Can abortion ever, or never, be justified? Should we care about people dying of hunger and disease in faraway countries? Do animals have rights, and if so, are they the same as or different from human rights? These questions – of immediate practical concern in the world we live in – are also the subject of philosophical inquiry.
So what, then, is philosophy? Is it a science? Is it an art? And how does it differ from religion?
Like science, philosophy seeks to find answers to questions by a process of investigation and argument, but it differs from science in that the questions it asks cannot be answered by means of practical experiment. Philosophical investigation is mental rather than experimental.
Like religion, philosophy considers the fundamental questions of life and death, of purpose and meaninglessness, of right and wrong. But unlike religion, philosophy addresses these questions by argument and demonstration, allowing no place to revelation and dogma.
Few people have regarded philosophy as an art-form, but the American philosopher Robert Nozick has suggested that, just as a composer works with musical themes, harmonic structures and metre, an artist with forms and colours, and a novelist with plots, characters and actions, so a philosopher works with ideas, concepts and questions which are moulded and shaped, developed and revised, ordered and reordered, and in so doing ‘sculptures a view’.
Philosophy in an informal sense is probably as old as civilization itself, but as a mental discipline it does not become clearly separate from religion until the 6th century BC, among the Greeks living in southern Italy and around the Aegean Sea. However, under the influence of Christianity, philosophy and religion become entangled once again during the Middle Ages, and philosophy as a separate enterprise independent of religion and dogma begins once more with Descartes in the 17th century.
The main branches of modern philosophy are metaphysics, which inquires into the nature of reality and includes ontology, concerned specifically with the nature of being; logic, which establishes the principles of valid reasoning; epistemology, which investigates the nature of knowledge; and ethics, the study of moral values and principles. There are, in addition, philosophies of many specific branches of human study and activity: for example, art (aesthetics), law (jurisprudence), politics, science, the mind, religion and language.
Not only are there several branches of philosophy, there are also many schools of philosophy. Among these are the Sceptics, who question whether it is possible to truly know anything; the Empiricists, who claim that all knowledge is based on experience; the Rationalists, who base knowledge on thought and reason; the Idealists, for whom what is real does not exist independently of the human mind; the Utilitarians, who relate the notions of ‘right’ and ‘wrong’ to what makes people happy or unhappy; and the Existentialists, who begin their philosophical investigations with the concerns of human beings finding themselves in an apparently meaningless world and having to deal with such matters as personal freedom and responsibility.
In the first half of the 20th century, one of the main focuses of philosophy in the English-speaking world was ‘analytic philosophy’, concerned with the careful analysis of language and the concepts it expresses, as in the work of Russell and Wittgenstein. Analytic philosophy remains dominant in the English-speaking philosophical world today, although its subject matter now ranges well beyond the confines of linguistic analysis, as for example in the work of Rawls and Nozick. Commonly contrasted with analytic philosophy is ‘continental philosophy’, European in origin though by no means limited to European philosophers. Concerned with the human condition in all its complexities, it is more metaphysical and speculative than analytical philosophy.
Philosophy has been described as being ‘brain-breakingly’ difficult. Indeed, C.E.M. Joad, a former professor of philosophy, once wrote that ‘most books on philosophy are unintelligible to most intelligent people’ and that ‘over half of what passes for philosophy is unreadable’, something he attributed in part to the abysmal writing-style of many philosophers.
Whether you find such an opinion depressing or reassuring, it certainly underlines the need for a book such as Philosophy. In these pages you will find clear and succinct outlines of the key thoughts of the leading philosophers from philosophy’s earliest stages right down to the 21st century. All the main branches of philosophy are covered, and all the main schools. And if, having read the articles in this book, you want to explore the writings of the philosophers themselves, then the ‘Essential reading’ boxes will guide you towards what you should look at next. Even if half of philosophy is unreadable, the other half is well worth getting to grips with.
ANSELM, ST
1033–1109
Born at Aosta in Burgundy, Anselm was a pious child and sought admission to the monastic life at the early age of 15. The local Abbot, however, refused him on his father’s insistence. After his mother’s death, Anselm took to travelling. Eventually he arrived at the Abbey of Bec and began studying under the renowned Prior Lanfranc. He eventually took his monastic orders in 1060. Only three years later, when Lanfranc was appointed Abbot of Caen, the young Anselm succeeded him as Prior, much to the chagrin of older and more established candidates for the position. During the next thirty years he wrote his philosophical and theological works and was appointed Abbot of Bec.
Now remembered as the father of the Scholastic tradition and Archbishop of Canterbury from 1093 until his death, Anselm is of philosophical interest mainly for his logical arguments in two major works, the Monologion (meaning ‘Soliloquy’) and the Proslogion (Discourse), both of which gave various arguments intended to prove the existence of God.
By the 12th century, the works of Plato and Aristotle had been rediscovered and reinterpreted by the scholastics who attempted to synthesize early Greek ideas with medieval theology. Following the Greek tradition, it is said that Anselm’s students had been concerned to hear a rational justification for the existence of God that did not rely merely on the acceptance of scripture or doctrinal teaching. Anselm’s most famous response to this challenge was to become known as ‘the ontological argument for the existence of God’ which has been called by some one of the most hotly debated issues in the history of philosophy.
Consider, invites Anselm, that by the term ‘God’ we mean something than which nothing greater can be thought of. Given that even the non-believer or, as Anselm calls him, the Fool, accepts that this is what the concept of God entails, the existence of God would seem to follow necessarily from the definition. For it would be a contradiction to suppose that God is on the one hand something than which nothing greater can be thought of and on the other hand does not exist. For a God thought of that does not really exist is not so great as one thought of that does exist, and since one can clearly think of God and suppose he exists, then something than which nothing greater can be thought of must be something that exists.
Anselm’s ontological argument is ingenious in its simplicity. While most people agree that there is something rather fishy about it, opinion has been divided as to exactly what is the matter with the argument. The earliest critic of Anselm was a contemporary Benedictine monk called Gaunilo of Marmoutiers. Gaunilo argued that if Anselm’s reasoning were correct, then one could conceive of a lost island that was the most perfect island there could ever be. Since by definition the island is the most perfect it must exist, for by Anselm’s reasoning it would be less than perfect if it did not. Thus, complained Gaunilo, Anselm’s reasoning licenses the existence of all sorts of imaginary objects and must therefore be faulty. In response, Anselm claimed that the quality of perfection is an attribute that only applies to God, and therefore his ontological argument cannot be used to prove the existence of imaginary islands or anything else.
St Anselm is shown here at work, surrounded by the accoutrements of his office, and entranced by a vision of the Virgin and Child.
Versions of Anselm’s ontological argument were later used by both St Thomas Aquinas and René Descartes and were, much later still, heavily criticized by Immanuel Kant. Kant’s principle complaint was that the concept of God as a perfect being does not necessarily entail that God exists since ‘existence’ is not a perfection. The concept of a perfect being that exists is no more or less great than the concept of a perfect being that does not exist.
Philosophers agree that the problem with Anselm’s argument revolves around the fact that we surely cannot ascertain whether something exists or not merely by analysing the meaning of a word or concept. However, exactly what logical error is being committed by attempting to do so has remained a cause of much dispute amongst philosophers and logicians.
The Abbey of Bec, where St Anselm lived and worked, eventually rising to the post of Abbot.
The argument was taken up again in more recent times, in the 1960s, when the philosopher Norman Malcolm revived a lesser known variant of Anselm’s argument which sidesteps the objections made by Kant and others.
According to Malcolm, Anselm argues in the Proslogion that if it is possible that a necessary being could exist, then it must exist, for it would be a contradiction to say a necessary being does not exist. God could only fail to exist if the concept of God was self-contradictory or nonsensical, and this, declares Malcolm, remains to be shown by opponents of the ontological argument.
ESSENTIAL READING
St Anselm wrote many religious books, including Cur Deus Homo (Why did God become Man?), but is best known today for his two philosophical works, Monologion and Proslogion, in which he attempted to prove the existence of God.
Monologion (1076)
In this book, Anselm argues that the concept of ‘goodness’ would not be possible if there were not some absolute standard, some ideal of goodness, which all other ‘goodnesses’ were a reflection of. That ideal of goodness is God.
Proslogion (1077–78)
Not entirely satisfied with his efforts in Monologion, Anselm tried another proof of God, known as the ontological argument, in his next book: if we can conceive of perfection, but it exists only in our minds, then it is less than perfect. Yet, we can conceive of perfection – so therefore perfection, or God, must exist.
AQUINAS, ST THOMAS
1225–1274
The favoured philosopher of the Catholic Church, Aquinas is principally remembered for reconciling the philosophy of Aristotle with Christian doctrine. Born in northern Sicily, he was educated first at the University of Naples and later at Cologne, and lectured at Paris and Naples. Aquinas was canonized in 1323 by Pope John XII.
While much of Aquinas’ work was Aristotelian in derivation, he also extended and clarified many of Aristotle’s ideas. Chief amongst Aquinas’ many achievements are the ‘Five Ways’, or proofs of the existence of God, from his Summa Theologica. The Five Ways are the clearest and most succinct attempt to prove the existence of God by means of logical argument.
In the first of the Five Ways, Aquinas says the existence of God can be proved by considering the concept of change. We can clearly see that some things in the world are in the process of change, and this change must be a result of something else, since a thing cannot change of itself. But the cause of the change itself, since in the process of change, must also be caused to change by something other than itself, and so on again, ad infinitum. Clearly, there must be something which is the cause of all change, but which itself does not undergo change. For, as Aquinas says, ‘if the hand does not move the stick, the stick will not move anything else’. The first mover, Aquinas concludes, is God.
In the second Way, arguing in a similar manner to the first, Aquinas notes that causes always operate in series, but there must be a first cause of the series or there could not be a series at all. Interestingly, both the first and second Ways proceed on the assumption that a thing cannot cause itself. Yet this is precisely his conclusion, that there is a thing which does cause itself, namely, God. Philosophers have criticized this form of arguing as confused, since the proposition that appears to be proven in the conclusion is the very same proposition denied in the argument.
A detail of Carlo Crivelli’s 1476 Demidoff Altarpiece showing Aquinas, who was canonized in 1323.
In the third Way, it is noted that we observe that things in the world come to be and pass away. But clearly not everything can be like this, for then there would have been a time when nothing existed. But if that were true then nothing could ever have come into being, since something cannot come from nothing. Therefore something must have always existed, and this is what people understand by God. The first, second and third Ways of Aquinas’ arguments are often called variations of a more general argument, the Cosmological Argument.
In the fourth Way, Aquinas offers a version of the Ontological Argument (see Anselm). In Aquinas’ version some things are noted to exhibit varying degrees of a quality. A thing may be more or less hot, more or less good, more or less noble. Such varying degrees of quality are caused by something that contains the most or perfect amount of that quality. For just as the sun is the hottest thing, and thus the cause of all other things being hot, so there must be some fully ‘good’ thing which makes all other things good. That which is most good is, of course, God.
Finally, in the fifth Way, Aquinas relies on Aristotle’s notion of ‘telos’ or purpose. All things aim towards some ultimate goal or end. But to be guided by a purpose or a goal implies some mind that directs or intends that purpose. That director is, once again, God. Versions of Aquinas’ cosmological and ontological arguments are still accepted by the Catholic Church today, though modern philosophers have almost unanimously rejected all five of Aquinas’ Ways.
ESSENTIAL READING
Summa contra Gentiles (1259–64)
This is Aquinas’ most important work. It aims to establish, mostly by philosophical argument, the truth of the Christian religion, proving the existence of God and then discussing the nature of God, creation and its purpose, the soul, ethics, sin, the Trinity, etc.
Summa Theologica (1266–73)
The Summary of Theology is a huge work, not what one might consider a summary. The first part discusses God, creation and human nature; the second part deals with morality; and the third part discusses Christ and the sacraments. Aquinas left the third part unfinished, having one day had a mystical vision, compared to which, he said, all he had written seemed like straw.
ARISTOTLE
384–322 BC
Aristotle’s achievements in the history and development of western thought are both stunning and unrivalled. More than just a philosopher, Aristotle was a scientist, astronomer, political theorist and the inventor of what is now called symbolic or formal logic. He wrote extensively on biology, psychology, ethics, physics, metaphysics and politics and set the terms of debate in all these areas right up to modern times. Indeed, his writings on justice are still required reading for undergraduates reading Law.
After his death his works were lost for some 200 years or so, but fortunately were rediscovered in Crete. Later translated into Latin by Boethius around AD500, Aristotle’s influence spread throughout Syria and Islam whilst Christian Europe ignored him in favour of Plato. Not until Thomas Aquinas reconciled Aristotle’s work with Christian doctrine in the 13th century did he become influential in western Europe.
Aristotle received his education from age seventeen in Plato’s ‘Academy’, where he stayed for some 20 years until Plato’s death.
Later he founded his own institution, ‘the Lyceum’, where he would expound a philosophy altogether different both in method and content from that of his former teacher.
More than any other philosopher before him, Aristotle made much of observation and strict classification of data in his studies. For this reason he is often considered as the father of empirical science and scientific method. Unlike his predecessor Plato, Aristotle always undertook his investigations by considering the regarded opinions of both experts and lay people, before detailing his own arguments, assuming that some grain of truth is likely to be found in commonly held ideas. Aristotle’s method was nothing if not rigorous and lacked the proselytizing tone of many of his predecessors.
Aristotle studied under Plato, at the latter’s famous Academy, for 20 years.

In contradistinction to both Plato and the Presocratics, Aristotle rejected the idea that the many diverse branches of human inquiry could, in principle, be subsumed under one discipline based on some universal philosophic principle.
Different sciences require different axioms and admit of varying degrees of precision according to their subject. Thus Aristotle denied there could be exact laws of human nature, whilst maintaining that certain metaphysical categories – such as quantity, quality, substance and relation – were applicable to the description of all phenomena.
If there is one common thread to much of Aristotle’s work it lies in his conception of teleology, or purpose. Perhaps as a result of his preoccupation with biological studies, Aristotle was impressed by the idea that both animate and inanimate behaviour is directed toward some final purpose (‘telos’) or goal.
It is common to explain the behaviour of people, institutions and nations in terms of purposes and goals (for example, John is sitting the bar exam to become a barrister; the school is holding a fête to raise funds for the roof; the country is going to war to protect its territory), and likewise modern evolutionary biology makes use of purposive explanation to account for the behaviour of, for instance, genes and genetic imperatives.
However, Aristotle thought the concept of purpose could be invoked to explain the behaviour of everything in the universe.
His reasoning lay in the idea that everything has a natural function and strives towards fulfilling or exhibiting that function, which is its best and most natural state. It is by means of the concept of function that Aristotle then ties his ethics to his physics, claiming that the natural function of man is to reason, and to reason well is to reason in accordance with virtue. Unlike the opposing ethical theories of Kant and Mill, both of which view actions as the subject of ethical judgements, Aristotle’s ethics focuses on the character of the agent as that which is morally good or morally bad. This so-called ‘virtue ethics’ was revived with much critical success by Alistair Macintyre in late 20th-century moral philosophy.
ESSENTIAL READING
Aristotle’s works cannot be precisely dated and it is likely that changes have been made to the texts down the ages. However, a substantial – and hugely influential – corpus has come down to us.
Nicomachean Ethics
One of the most important and influential works on ethics that has ever been written, the Ethics contains a discussion on virtue and its relationship to well-being and happiness. Aristotle’s ethical views show a clear understanding of human nature and psychology.
Politics
In his Politics, Aristotle discusses the ideal city-state, and classifies and discusses the merits and demerits of various types of government. The book includes a defence of slavery.
Physics
In this book Aristotle discusses topics such as matter, form, causation, space, time and motion. The book is also interesting for its discussion of the nature of explanation.
ARNAULD, ANTOINE
1612–1694
Last-born son of a lawyer who fathered twenty children, Arnauld became a theologian, logician and philosopher. He collaborated with both Nicole and Pascal on their famous The Art of Thinking, which later became known as ‘the Port Royal Logic’ or sometimes just ‘The Logic’. He is also remembered as the author of several of the replies to Descartes’ Meditations on First Philosophy, gaining in the process a reputation as an intellectually rigorous and perceptive critic, and bringing attention to the problem now known as ‘the Cartesian circle’.
Like Descartes, Arnauld is a firm rationalist. In The Art of Thinking, he proclaims that the main aim of logic is to inculcate clear thinking. Thus he writes, ‘nothing is more to be esteemed than aptness in discerning the true from the false. Other qualities of mind are of limited use, but precision of thought is essential to every aspect and walk of life. To distinguish truth from error is difficult not only in the sciences but also in the everyday affairs men engage in and discuss. Men are everywhere confronted with alternative routes – some true and others false – and reason must choose between them. Who chooses well has a sound mind, who chooses ill a defective one. Capacity for discerning the truth is the most important measure of minds.’
The Art of Thinking consists of four parts corresponding to the principal operations of the mind: conceiving, judging, reasoning and ordering. Conceiving and judging imply a knowledge of language, since it is concepts and propositions, essentially linguistic items, that are conceived and judged. Reasoning is a higher-level function of conceiving and judging, required when the concepts that form a proposition are not sufficiently clear for a judgement to be made. Finally, ordering is a mental activity which reflects the method of the new inductive sciences.
Arnauld accepts the general tenets of Cartesian thought. In line with Descartes’ ontological dualism, Arnauld commits himself to the idea that speech is part of the material world and bound by its laws, but thought, belonging to the essence of the mind, is not so constricted. This leads to a distinction in Arnauld’s work between grammar on the one hand, which belongs to speech; and logic, which belongs to the realm of thought. In the four-fold classification of The Logic, Arnauld places logic itself firmly within the faculty of reason, but insists that reasoning is merely an extension of judging.
This idea is important for it reflects one side of a foundational debate concerning the status of logic. Is logic, as Arnauld would have it, merely a tool of clear thinking in order to aid rhetoric, or does it reflect universal laws of thought that correspond to reality? This latter view, to which Arnauld and the Port Royal logicians were hostile, holds that there are three laws of thought that are necessary principles for any rational creature, even God. These are the law of non-contradiction, the law of identity, and the law of the excluded middle. These state respectively that a proposition cannot be simultaneously asserted and denied; that if A is identical
