Now all this is very well as far as it goes; and were there not one thing lacking, it would be just the answer that we are at present so anxious to elicit. But the one thing lacking, is enough to make it valueless. It may mean a great deal; but there is no possibility of saying exactly what it means. Before we can begin to strive towards the 'highest good,' we must know something of what this 'highest good' is. We must make this 'higher ideal' stand and unfold itself. If it cannot be made to do this, if it vanishes into mist as we near it, and takes a different shape to each of us as we recede from it; still more, if only some can see it, and to others it is quite invisible--then we must simply set it down as an illusion, and waste no more time in pursuit of it. But that it is not an illusion is the great positivist claim for it. Heaven and the love of God, we are told, were illusions. This 'highest good' we are offered, stands out in clear contradistinction to these. It is an actual attainable thing, a thing for flesh and blood creatures; it is to be won and enjoyed by them in their common daily life. It is, as its prophets distinctly and unanimously tell us, some form of happiness that results in this life to us, from certain conduct; it is a thing essentially for the present; and '_it is obviously_,' says Professor Huxley, '_in no way affected by abbreviation or prolongation of our conscious life_.' This being the case, it is clearly not unreasonable to demand some explicit account of it; or if no sound account of it be extant, to enquire diligently what sort of account of it is possible. And let it be remembered that to make this demand is in no way to violate the great rule of Aristotle, and to demand a greater accuracy than the nature of the subject will admit of. The 'highest good,' it is quite possible, may be a vague thing; not capable, like a figure in Euclid, of being defined exactly. But many vague things can be described exactly enough for all practical purposes. They can be described so that we at once know what is meant, and so that we can at once find and recognise them. Feelings, characters, and personal appearance are things of this sort; so too is the taste of food, the style of furniture, or the general tone and tenour of our life, under various circumstances. And the 'good' we are now considering can surely be not less describable than these. When therefore our exact thinkers speak to us about the highest happiness, we want to know what meaning they attach to the words. Has Professor Huxley, for instance, ever enjoyed it himself, or does he ever hope to do so? If so, when, where, and how? What must be done to get it, and what must be left undone? And when it is got, what will it be like? Is it something brief, rapturous, and intermittent, as the language often used about it might seem to suggest to one? Is it known only in brief moments of Neoplatonic ecstasy, to which all the acts of life should be
