Religion is still useful among the herd - that it helps their orderly conduct as nothing else could. The crude human animal is in-eradicably superstitious, and there is every biological reason why they should be. Take away his Christian god and saints, and he will worship something else.
Animals have these advantages over man: they never hear the clock strike, they die without any idea of death, they have no theologians to instruct them, their last moments are not disturbed by unwelcome and unpleasant ceremonies, their funerals cost them nothing, and no one starts lawsuits over their wills.
cruelty to animals is contrary to man's duty to himself, because it deadens in him the feeling of sympathy for their sufferings, and thus a natural tendency that is very useful to morality in relation to other human beings is weakened.
This is what you shall do: Love the earth and sun and the animals, despise riches, give alms to every one that asks, stand up for the stupid and crazy, devote your income and labor to others, hate tyrants, argue not concerning God, have patience and indulgence toward the people.
The perfect woman is a higher type of humanity than the perfect man, and also something much rarer. The natural history of animals furnishes grounds in support of this theory.
A thing may be too sad to be believed or too wicked to be believed or too good to be believed; but it cannot be too absurd to be believed in this planet of frogs and elephants, of crocodiles and cuttle-fish.
Nature has willed that man should, by himself, produce everything that goes beyond the mechanical ordering of his animal existence, and that he should partake of no other happiness or perfection than that which he himself, independently of instinct, has created by his own reason.
What strength belongs to every plant and animal in nature. The tree or the brook has no duplicity, no pretentiousness, no show. It is, with all its might and main, what it is, and makes one and the same impression and effect at all times. All the thoughts of a turtle are turtle's, and of a rabbit, rabbit's. But a man is broken and dissipated by the giddiness of his will; he does not throw himself into his judgments; his genius leads him one way but 't is likely his trade or politics in quite another.
A man that is endued with the powers of reason, by which he is capable of knowing, serving, glorifying, and enjoying his Maker, and yet lives without God in the world, is certainly the most despicable and the most miserable animal under the sun.
Most persons think that a state in order to be happy ought to be large; but even if they are right, they have no idea of what is a large and what a small state.... To the size of states there is a limit, as there is to other things, plants, animals, implements; for none of these retain their natural power when they are too large or too small, but they either wholly lose their nature, or are spoiled.
