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.
Let us guard against saying that there are laws in nature. There are merely necessities: there is no one who commands, no one whoobeys, no one who transgresses. Once you understand that there are no purposes, then you also understand that nothing is accidental: for it is only in a world of purposes that the word "accident" makes sense.
If Natur has gifted a man with powers of argeyment, a man has a right to make the best of 'em, and has not a right to stand on false delicacy, and deny that he is so gifted; for that is a turning of his back on Natur, a flouting of her, a slighting of her precious caskets, and a proving of one's self to be a swine that isn't worth her scattering pearls before.
[T]hro this Air, this Ocean, and this Earth, All Nature quick, and bursting into birth. Above, how high progressive life may go? Around how wide? how deep extend below? Vast Chain of Being! which from God began, Ethereal Essence, Spirit, Substance, Man, Beast, Bird, Fish, Insect! what no Eye can see, No Glass can reach! from Infinite to Thee! From Thee to Nothing.... From Natures Chain whatever Link you strike, Tenth, or ten thousandth, breaks the chain alike.... All are but parts of one stupendous Whole: Whose Body Nature is, and God the Soul.
The white face of the winter day came sluggishly on, veiled in a frosty mist; and the shadowy ships in the river slowly changed to black substances; and the sun, blood-red on the eastern marshes behind dark masts and yards, seemed filled with the ruins of a forest it had set on fire.
Look round and round upon this bare bleak plain, and see even here, upon a winter's day, how beautiful the shadows are! Alas! It is the nature of their kind to be so. The loveliest things in life... are but shadows; and they come and go, and change and fade away, as rapidly as these.
A human being is a part of the whole called by us universe; a part limited in time and space. He experiences himself, his thoughts, and his feelings as something separate from the rest - a kind of optical delusion of consciousness.
The notion that we would condition Iran not getting nuclear weapons in a verifiable deal on Iran recognizing Israel is really akin to saying that we won't sign a deal unless the nature of the Iranian regime completely transforms. And that is, I think, a fundamental misjudgment.
