"That man, as a 'political animal,' is susceptible of a vast amount of improvement, by education, by instruction, and by the application of his intelligence to the adaptation of the conditions of life to his higher needs, I entertain not the slightest doubt. But, so long as he remains liable to error, intellectual or moral; so long as he is compelled to be perpetually on guard against the cosmic forces, whose ends are not his ends, without and within himself; so long as he is haunted by inexpugnable memories and hopeless aspirations; so long as the recognition of his intellectual limitations forces him to acknowledge his incapacity to penetrate the mystery of existence; the prospect of attaining untroubled happiness, or of a state which can, even remotely, deserve the title of perfection, appears to me to be as misleading an illusion as ever was dangled before the eyes of poor humanity. And there have been many of them. That which lies before the human race is a constant struggle to maintain and improve, in opposition to the State of Nature, the State of Art of an organised polity; in which, and by which, man may develop a worthy civilisation, capable of maintaining and constantly improving itself, until the evolution of our globe shall have entered so far upon its downward course that the cosmic process resumes its sway; and, once more, the State of Nature prevails over the surface of our planet." But only those of low ideals would seek in this impermanence of things excuse for inaction; or worse, for self-indulgence. The world will last a very long time yet, and afford scope for battle against the wrongs done by man to man. Even were it and ourselves to perish to-morrow, our duty is clear while the chance of doing it may be ours. Clifford,--dead before his prime, before the rich promise of his genius had its full fruitage,--speaking of the inevitable end of the earth "and all the consciousness of men" reminds us, in his essay on The First and Last Catastrophe, that we are helped in facing the fact "by the words of Spinoza: 'The free man thinks of nothing so little as of death, and his wisdom is a meditation not of death but of life.'" "Our interest," Clifford adds, "lies with so much of the past as may serve to guide our actions in the present, and to intensify our pious allegiance to the fathers who have gone before us and the brethren who are with us; and our interest lies with so much of the future as we may hope will be appreciably affected by our good actions now. Do I seem to say, 'Let us eat and drink, for to-morrow we die?' Far from it; on the contrary I say, 'Let us take hands and help, for this day we are alive together.'" Evolution and Ethics was Huxley's last important deliverance, since the completion of his reply to Mr. Balfour's "quaintly entitled" Foundations of Belief was arrested by his death on the 30th of June, 1895.
