How many times it thundered before Franklin took the hint! How many apples fell on Newton's head before he took the hint! Nature is always hinting at us. It hints over and over again. And suddenly we take the hint.
The same stream of life that runs through my veins night and day runs through the world and dances in rhythmic measures. It is the same life that shoots in joy through the dust of the earth in numberless blades of grass and breaks into tumultuous waves of leaves and flowers.
Our moods do not believe in each other. To-day I am full of thoughts, and can write what I please. I see no reason why I should not have the same thought, the same power of expression, to-morrow. What I write, whilst I write it, seems the most natural thing in the world; but yesterday I saw a dreary vacuity in this direction in which now I see so much; and a month hence, I doubt not, I shall wonder who he was that wrote so many continuous pages. Alas for this infirm faith, this will not strenuous, this vast ebb of a vast flow! I am God in nature; I am a weed by the wall.
Reason is a supple nymph, and slippery as a fish by nature. She had as leave give her kiss to an absurdity any day, as to syllogistic truth. The absurdity may turn out truer.
TZETZE (or TSETSE) FLY, n. An African insect ("Glossina morsitans") whose bite is commonly regarded as nature's most efficacious remedy for insomnia, though some patients prefer that of the American novelist ("Mendax interminabilis").

After you have exhausted what there is in business, politics, conviviality, and so on - have found that none of these finally satisfy, or permanently wear - what remains? Nature remains.
