By labor and intent study (which I take to be my portion in this life), joined with the strong propensity of nature, I might perhaps leave something so written to after-times, as they should not willingly let it die.
MIND, n. A mysterious form of matter secreted by the brain. Its chief activity consists in the endeavour to ascertain its own nature, the futility of the attempt being due to the fact that it has nothing but itself to know itself with.
From the oyster to the eagle, from the swine to the tiger, all animals are to be found in men and each of them exists in some man, sometimes several at the time. Animals are nothing but the portrayal of our virtues and vices made manifest to our eyes, the visible reflections of our souls. God displays them to us to give us food for thought.
To be sure, it is not the fruits of scientific research that elevate a man and enrich his nature, but the urge to understand, the intellectual work, creative or receptive.
Nature reaches out to us with welcoming arms, and bids us enjoy her beauty; but we dread her silence and rush into the crowded cities, there to huddle like sheep fleeing from a ferocious wolf.

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.
Every blade of grass, every insect, ant, and golden bee, all so amazingly know their path, though they have not intelligence, they bear witness to the mystery of God and continually accomplish it themselves.
My scientific work is motivated by an irresistible longing to understand the secrets of nature and by no other feeling. My love for justice and striving to contribute towards the improvement of human conditions are quite independent from my scientific interests.
The animals of the world exist for their own reasons. They were not made for humans any more than black people were made for white, or women created for men.
Huge knots of sea-weed hung upon the jagged and pointed stones, trembling in every breath of wind; and the green ivy clung mournfully round the dark and ruined battlements. Behind it rose the ancient castle, its towers roofless, and its massive walls crumbling away, but telling us proudly of its own might and strength, as when, seven hundred years ago, it rang with the clash of arms, or resounded with the noise of feasting and revelry.
