“All knowledge that is not the real product of observation, or of consequences deduced from observation, is entirely groundless and illusory.”

The form follows the function.

It is not always the magnitude of the differences observed between species that must determine specific distinctions, but the constant preservation of those differences in reproduction.

It is not enough to discover and prove a useful truth previously unknown, but that it is necessary also to be able to propagate it and get it recognized.

Habits form a second nature.

What nature does in the course of long periods we do every day when we suddenly change the environment in which some species of living plant is situated.

All known living bodies are sharply divided into two special kingdoms, based upon the essential differences which distinguish animals from plants, and in spite of what has been said, I am convinced that these two kingdoms do not really merge into one another at any point.

It is not the organs-that is, the character and form of the animal’s bodily parts-that have given rise to its habits and particular structures. It is the habits and manner of life and the conditions in which its ancestors lived that have in the course of time fashioned its bodily form, its organs and qualities.

The glorious thing for you always has consequences for others.

They obviously collected a lot of votes, but these monies could not solve the structural problems that these people face. But the only result, the only consequence, was that a big sum from the budget was wasted this way.

The world’s problems are, by and large, human problems-the unavoidable consequence of egoic sleepwalking. If we care to look, all the signs are present to suggest that we are not only sleepwalking, but at times borderline insane as well.

You are free to choose but you are not free to choose the consequences of that choice.

You are free to choose. You are not free not to choose. No choice is a choice.

To rescue people from the natural consequences of their behavior is to render them powerless.

The ultimate cause of human disease is the consequence of our transgression of the universal laws of life.

You are not aware of the consequences that would result (if you were granted what you desire) because what you seek might be to your detriment.
