From a letter to William James from a friend, which James discusses in Lecture 8 of Pragmatism:
I believe in pluralism; I believe that in our search for truth we leap from one floating cake of ice to another, on an infinite sea, and that by each of our acts we make new truths possible and old ones impossible; I believe that each man is responsible for making the universe better, and that if he does not do this it will be in so far left undone.And from the same lecture, William James summation of his own beliefs:
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. . . .
Of course as human beings we can be healthy minds on one day and sick souls on the next; and as amateur dabblers in philosophy we may perhaps be allowed to call ourselves monistic pluralists, or free-will determinists, or whatever else may occur to us of a reconciling kind. But as philosophers aiming at clearness and consistency, and feeling the pragmatistic need of squaring truth with truth, the question is forced upon us of frankly adopting either the tender or the robustious type of thought. In particular this query has always come home to me: May not the claims of tender-mindedness go too far? May not the notion of a world already saved in toto anyhow, be too saccharine to stand? May not religious optimism be too idyllic? Must all be saved? Is no price to be paid in the work of salvation? Is the last word sweet? Is all 'yes, yes' in the universe? Doesn't the fact of 'no' stand at the very core of life? Doesn't the very 'seriousness' that we attribute to life mean that ineluctable noes and losses form a part of it, that there are genuine sacrifices somewhere, and that something permanently drastic and bitter always remains at the bottom of its cup?
I cannot speak officially as a pragmatist here; all I can say is that my own pragmatism offers no objection to my taking sides with this more moralistic view, and giving up the claim of total reconciliation. The possibility of this is involved in the pragmatistic willingness to treat pluralism as a serious hypothesis. In the end it is our faith and not our logic that decides such questions, and I deny the right of any pretended logic to veto my own faith. I find myself willing to take the universe to be really dangerous and adventurous, without therefore backing out and crying 'no play! I am willing to think that the prodigal-son attitude, open to us as it is in many vicissitudes, is not the right and final attitude towards the whole of life. I am willing that there should be real losses and real losers, and no total preservation of all that is. I can believe in the ideal as an ultimate, not as an origin, and as an extract, not the whole. When the cup is poured off, the dregs are left behind forever, but the possibility of what is poured off is sweet enough to accept.
As a matter of fact countless human imaginations live in this moralistic and epic kind of a universe, and find its disseminated and strungalong successes sufficient for their rational needs. There is a finely translated epigram in the greek anthology which admirably expresses this state of mind, this acceptance of loss as unatoned for, even tho the lost element might be one's self:
A shipwrecked sailor, buried on this coast,
Bids you set sail.
Full many a gallant ship, when we were lost,
Weathered the gale.
