May we not imagine that possibly this earthly life of ours is to the other life what sleeping is to waking? May not all our life be a dream and death… - Miguel de Unamuno

And the soul, my soul at least, longs for something else, not absorption, not quietude, not peace, not appeasement, it longs ever to approach and never to arrive, it longs for the never-ending longing, for an eternal hope which is eternally renewed but never wholly fulfilled. And together with all this, it longs for an eternal lack of something and an eternal suffering. A suffering, a pain, thanks to which it grows without ceasing in consciousness and longing. Do not write upon the gate of heaven that sentence which Dante placed over the threshold of hell, Lasciate ogni speranza! [Lasciate ogne speranza, voi ch'intrate: All hope abandon, ye who enter in] Do not destroy time!

Knowledge is employed in the service of the necessity of life and primarily in the service of the instinct of personal preservation. The necessity and this instinct have created in man the organs of knowledge and given them such capacity as they possess. Man sees, hears, touches, tastes and smells that which it is necessary for him to see, hear, touch, taste and smell in order to preserve his life. The decay or loss of any of these senses increases the risks with which his life is environed, and if it increases them less in the state of society in which we are actually living, the reason is that some see, hear, touch, taste and smell for others. A blind man, by himself and without a guide, could not live long. Society is an additional sense; it is the true common sense.

A faith which does not doubt is a dead faith.
