There is no pre-established harmony between the furtherance of truth and the well-being of mankind.
What then is truth? A movable host of metaphors, metonymies, and anthropomorphisms: in short, a sum of human relations which have been poetically and rhetorically intensified, transferred, and embellished, and which, after long usage, seem to a people to be fixed, canonical, and binding. Truths are illusions which we have forgotten are illusions â€” they are metaphors that have become worn out and have been drained of sensuous force.
Hope, in its stronger forms, is a great deal more powerful stimulans to life than any sort of realized joy can ever be. Man must be sustained in suffering by a hope so high that no conflict with actuality can dash it - so high, indeed, that no fulfilment can satisfy it: a hope reaching out beyond this world.
