Philosophy: A Very Short Introduction

you that the purpose of philosophy is the relief of human suffering and the attainment of ‘enlightenment’; a Hindu will say something similar, if in slightly different terminology; both will speak of escape from a supposed cycle of death and rebirth in which one’s moral deserts determine one’s future forms. An Epicurean (if you can find one nowadays) will pooh-pooh all the stuff about rebirth, but offer you a recipe for maximizing pleasure and minimizing suffering in this your one and only life.
Not all philosophy has sprung out of a need for a comprehensive way of living and dying. But most of the philosophy that has lasted has arisen from some pressing motivation or deeply felt belief—seeking truth and wisdom purely for their own sakes may be a nice idea, but history suggests that a nice idea is pretty much all it is. Thus classical Indian philosophy represents the internal struggle between the schools of Hinduism, and between them all and the Buddhists, for intellectual supremacy; the battle for the preferred balance between human reason and scriptural revelation has been fought in many cultures, and in some is still going on; Thomas Hobbes’s famous political theory (we shall be seeing more of it later) tries to teach us the lessons he felt had to be learnt in the aftermath of the English Civil War; Descartes and many of his contemporaries wanted medieval views, rooted nearly two thousand years back in the work of Aristotle, to move aside and make room for a modern conception of science; Kant sought to advance the autonomy of the individual in the face of illiberal and autocratic regimes, Marx to liberate the working classes from poverty and drudgery, feminists of all epochs to improve the status of women. None of these people were just solving little puzzles (though they did sometimes have to solve little puzzles on the way); they entered into debate in order to change the course of civilization.
The reader will notice that I haven’t made any attempt to define philosophy, but have just implied that it is an extremely broad term covering a very wide range of intellectual activities. Some think that nothing is to be gained from trying to define it. I can sympathize with that thought, since most attempts strike me as much too restrictive, and therefore harmful rather than helpful in so far as they have any effect at all. But I will at least have a shot at saying what philosophy is; whether what I have to offer counts as a definition or not is something about which we needn’t, indeed positively shouldn’t, bother too much.
Once, a very long time ago, our ancestors were animals, and simply did whatever came naturally without noticing that that was what they were doing, or indeed without noticing that they were doing anything at all. Then, somehow, they acquired the capacities to ask why things happen (as opposed to just registering that they do), and to look at themselves and their actions. That is not as big a jump as may at first sight appear. Starting to ask why things happen is in the first place only a matter of becoming a little more conscious of aspects of one’s own behaviour. A hunting animal that follows a scent is acting as if aware that the scent is there because its prey has recently passed that way—and it is because that really is why the scent is there that it often succeeds in its hunt. Knowledge of this sort of connection can be very useful: it tells us what to expect. Furthermore, to know that A happens because B happened may improve your control over things: in some cases B will be something that you can bring about, or prevent—which will be very useful if A is something you want, or want to avoid. Many of these connections animals, humans included, follow naturally and unconsciously. And the practice, once one is aware of it, can valuably be extended by consciously raising such questions in cases where we do not have conveniently built-in answers.

There could be no guarantee, however, that this generally valuable tendency would always pay off, let alone always pay off quickly. Asking why fruit falls off a branch pretty soon leads one to shake the tree. Asking why it rains, or why it doesn’t rain, takes us into a different league, especially when the real motive underlying the question is whether we can influence whether it rains or not. Often we can influence events, and it may well pay to develop the habit of asking, when things (a hunting expedition, for example) have gone wrong, whether that was because we failed in our part of the performance, as opposed to being defeated by matters beyond our control. That same useful habit might have generated the thought that a drought is to some extent due to a failure of ours—and now what failure, what have we done wrong? And then an idea might crop up which served us well in our infancy: there are parents, who do things for us that we can’t do ourselves, but only if we’ve been good and they aren’t cross with us. Might there be beings that decide whether the rain falls, and shouldn’t we be trying to get on the right side of them?
That is all it would take for human beings to be launched into the investigation of nature and belief in the supernatural. So as their mental capacities developed our ancestors found their power increasing; but they also found themselves confronted by options and mysteries—life raised a host of questions, where previously it had simply been lived, unquestioningly. It is just as well that all this happened gradually, but even so
