But this talk of rationality is a parenthesis and a digression. What we were discussing was the idea of a world growing not integrally but piecemeal by the contributions of its several parts. Take the hypothesis seriously and as a live one. Suppose that the world's author put the case to you before creation, saying: "I am going to make a world not certain to be saved, a world the perfection of which shall be conditional merely, the condition being that each several agent does its own 'level best.' I offer you the chance of taking part in such a world. Its safety, you see, is unwarranted. It is a real adventure, with real danger, yet it may win through. It is a social scheme of co-operative work genuinely to be done. Will you join the procession? Will you trust yourself and trust the other agents enough to face the risk?" Should you in all seriousness, if participation in such a world were proposed to you, feel bound to reject it as not safe enough? Would you say that, rather than be part and parcel of so fundamentally pluralistic and irrational a universe, you preferred to relapse into the slumber of nonentity from which you had been momentarily aroused by the tempter's voice? Of course if you are normally constituted, you would do nothing of the sort. There is a healthy-minded buoyancy in most of us which such a universe would exactly fit. We would therefore accept the offer--"Top! und schlag auf schlag!" It would be just like the world we practically live in; and loyalty to our old nurse Nature would forbid us to say no. The world proposed would seem 'rational' to us in the most living way. Most of us, I say, would therefore welcome the proposition and add our fiat to the fiat of the creator. Yet perhaps some would not; for there are morbid minds in every human collection, and to them the prospect of a universe with only a fighting chance of safety would probably make no appeal. There are moments of discouragement in us all, when we are sick of self and tired of vainly striving. Our own life breaks down, and we fall into the attitude of the prodigal son. We mistrust the chances of things. We want a universe where we can just give up, fall on our father's neck, and be absorbed into the absolute life as a drop of water melts into the river or the sea. The peace and rest, the security desiderated at such moments is security against the bewildering accidents of so much finite experience. Nirvana means safety from this everlasting round of adventures of which the world of sense consists. The hindoo and the buddhist, for this is essentially their attitude, are simply afraid, afraid of more experience, afraid of life.
