Miguel de Unamuno (1864 – 1936)
Spanish essayist, novelist, poet, playwright and philosopher.
What the sorrowful Jew of Amsterdam called the essence of a thing, the effort that it makes to persist indefinitely in its own being, self-love, the longing for immortality, is it not perhaps the primal and fundamental condition of all reflective or human knowledge? And is it not therefore the true base, the real starting-point, of all philosophy, although the philosophers, perverted by intellectualism, do not recognize it?
We must needs believe in the other life, in the eternal life beyond the grave. ...And we must needs believe in that other life, perhaps, in order that we may deserve it, in order that we may obtain it, for it may be that he neither deserves it nor will obtain it who does not passionately desire it above reason and, if need be, against reason.
Man is said to be a reasoning animal. I do not know why he has not been defined as an affective or feeling animal. Perhaps that which differentiates him from other animals is feeling rather than reason. More often I have seen a cat reason than laugh or weep. Perhaps it weeps or laughs inwardly — but then perhaps, also inwardly, the crab resolves equations of the second degree.
