“What we do see depends mainly on what we look for. ... In the same field the farmer will notice the crop, the geologists the fossils, botanists the flowers, artists the colouring, sportmen the cover for the game. Though we may all look at the same things, it does not all follow that we should see them.”
― John Lubbock, The Beauties of Nature and the Wonders of the World We Live in

“[...]the only people for me are the mad ones, the ones who are mad to live, mad to talk, mad to be saved, desirous of everything at the same time, the ones who never yawn or say a commonplace thing, but burn, burn, burn like fabulous yellow roman candles exploding like spiders across the stars and in the middle you see the blue centerlight pop and everybody goes “Awww!”
― Jack Kerouac, On the Road

“Nothing, in truth, can ever replace a lost companion. Old comrades cannot be manufactured. There is nothing that can equal the treasure of so many shared memories, so many bad times endured together, so many quarrels, reconciliations, heartfelt impulses. Friendships like that cannot be reconstructed. If you plant an oak, you will hope in vain to sit soon under its shade.
For such is life. We grow rich as we plant through the early years, but then come the years when time undoes our work and cuts down our trees. One by one our comrades deprive us of their shade, and within our mourning we always feel now the secret grief of growing old.
If I search among my memories for those whose taste is lasting, if I write the balance sheet of the moments that truly counted, I surely find those that no fortune could have bought me. You cannot buy the friendship of a companion bound to you forever by ordeals endured together.”
― Antoine de Saint-Exupéry, Wind, Sand and Stars

“Take the case of courage. No quality has ever so much addled the brains and tangled the definitions of merely rational sages. Courage is almost a contradiction in terms. It means a strong desire to live taking the form of a readiness to die. 'He that will lose his life, the same shall save it,' is not a piece of mysticism for saints and heroes. It is a piece of everyday advice for sailors or mountaineers. It might be printed in an Alpine guide or a drill book. This paradox is the whole principle of courage; even of quite earthly or brutal courage. A man cut off by the sea may save his life if we will risk it on the precipice.

He can only get away from death by continually stepping within an inch of it. A soldier surrounded by enemies, if he is to cut his way out, needs to combine a strong desire for living with a strange carelessness about dying. He must not merely cling to life, for then he will be a coward, and will not escape. He must not merely wait for death, for then he will be a suicide, and will not escape. He must seek his life in a spirit of furious indifference to it; he must desire life like water and yet drink death like wine. No philosopher, I fancy, has ever expressed this romantic riddle with adequate lucidity, and I certainly have not done so. But Christianity has done more: it has marked the limits of it in the awful graves of the suicide and the hero, showing the distance between him who dies for the sake of living and him who dies for the sake of dying.”
― G.K. Chesterton, Orthodoxy
