"And suppose that he is forced into the presence of the sun himself, is he not likely to be pained and irritated? When he approaches the light his eyes will be dazzled, and he will not be able to see anything at all of what are now called realities."
The thought that Plato has expressed in this wonderful allegory has entered deeply into all philosophy. What we first take for reality is merely a shadow world. But in Plato's view it is the intellect which gives us the means of escape, the power to turn from the illusion to behold the reality. It is not until now that philosophy has sought the clue to the illusion in the nature of the intellect itself. The very instrument of truth is unfitted to reveal to us the reality as it is, because its nature and purpose is to transform reality, to make reality appear in a form which, though of paramount importance to us as active beings, is essentially an illusion. The intellectual bent of our mind leads us away from, and not towards a vision of reality in its purity. The more our intellect progresses, and the more and more clearly we { 69} see into a greater and ever greater number of things, the farther are we from, and not the nearer to a grasp of reality as it is. To obtain this vision of reality we have to turn away from the intellect and find ourselves again in that wider life out of which the intellect is formed. Life, as it lives, is an intuition that is nonintellectual.
"Human intelligence," writes Bergson, "is not at all what Plato taught in the allegory of the cave. Its function is not to look at passing shadows, nor yet to turn itself round and contemplate the glaring sun. It has something else to do. Harnessed, like yoked oxen, to a heavy task, we feel the play of our muscles and joints, the weight of the plough, and the resistance of the soil. To act and to know that we are acting, to come into touch with reality and even to live it, but only in the measure in which it concerns the work that is being accomplished and the furrow that is being ploughed, such is the function of human intelligence."
The illusion to which our intellectual nature subjects us is the necessity we are under to regard the things of the universe as more ultimate, as more fundamental than the movement which actuates the universe. It seems to us impossible that there could exist movement or change, unless there already existed things to be moved or changed, things whose nature is not altered, but only their form and their external relations, when they are moved or changed. This necessity of thought seems to have received authoritative recognition in all attempts, religious and scientific, to conceive origins. Thus we read in the Book of Genesis:
