Love every leaf, every ray of light. Love the animals, love the plants, love each separate thing. Loving all, you will perceive the mystery of God in all.
Concerning the generation of animals akin to them, as hornets and wasps, the facts in all cases are similar to a certain extent, but are devoid of the extraordinary features which characterize bees; this we should expect, for they have nothing divine about them as the bees have.
Man is by nature a social animal; an individual who is unsocial naturally and not accidentally is either beneath our notice or more than human. Society is something that precedes the individual. Anyone who either cannot lead the common life or is so self-sufficient as not to need to, and therefore does not partake of society, is either a beast or a god.
Compassion for animals is intimately associated with goodness of character, and it may be confidently asserted that he who is cruel to animals cannot be a good man.
The problem isn't materialism as such. Rather it is the underlying assumption that full satisfaction can arise from gratifying the senses alone.

The animal man lives in the senses. If he does not get enough to eat, he is miserable; or if something happens to his body, he is miserable. In the senses both his misery and his happiness begin and end.
In a civilized and cultivated country wild animals only continue to exist at all when preserved by sportsmen. the excellent people who protest against all hunting, and consider sportsmen as enemies of wild life, are ignorant of the fact that in reality the genuine sportsman is by all odds the most important factor in keeping the larger and more valuable wild creatures from total extermination.
Strictly speaking, no activity and no industry is possible without a certain amount of violence, no matter how little. Even the very process of living is impossible without a certain amount of violence. What we have to do is to minimize it to the greatest extent possible.
My days I devote to reading and experiments in chemistry, and I spend many of the clear nights in the study of astronomy. There is, though I do not know how there is or why there is, a sense of infinite peace and protection in the glittering hosts of heaven. There it must be, I think, in the vast and eternal laws of matter, and not in the daily cares and sins and troubles of men, that whatever is more than animal within us must find its solace and its hope.
