Science is the language of the temporal world; love is that of the spiritual world. Man, indeed, describes more than he explains; while the angelic spirit sees and understands. Science saddens man; love enraptures the angel; science is still seeking; love has found.
What patient can trust the knowledge of a physician without reputation or furniture, in a period when publicity is all-powerful and when the government gilds the lamp posts on the Place de la Concorde in order to dazzle the poor?
Sometimes, one gesture comprises an entire drama, the accent of one word ruins an entire existence, and the indifference of one glance kills the happiest passion.
Thinking is seeing.... Every human science is based on deduction, which is a slow process of seeing by which we work up from the effect to the cause; or, in a wider sense, all poetry like every work of art proceeds from a swift vision of things.
All men can bear a familiar, definite misfortune better than the cruel alternations of a fate which, from one moment to another, brings excessive joy or sorrow.
But also remember: if you have any genuine feelings, hide them like treasure; never let anyone so much as suspect them, or you're lost. Instead of being the executioner, you'll be the victim. And if you ever fall in love, keep that absolutely secret! Never breathe a word until you're completely sure of the person to whom you open your heart. And to protect that love, even before you feel it, learn to despise the world.
