Man, biologically considered ... is simply the most formidable of all beasts of prey, and, indeed, the only one that preys systematically on its own kind.

It is true that so far as wealth gives time for ideal ends and exercise to ideal energies, wealth is better than poverty and ought to be chosen. But wealth does this in only a portion of the actual cases. Elsewhere the desire to gain wealth and the fear to lose it are our chief breeders of cowardice and propagators of corruption. There must be thousands of conjunctures in which a wealth-bound man must be a slave, whilst a man for whom poverty has no terrors becomes a freeman.

The minute a man ceases to grow, no matter what his years, that minute he begins to be old.

The man whose acquisitions stick is the man who is always achieving and advancing whilst his neighbors, spending most of their time in relearning what they once knew but have forgotten, simply hold their own.

One of the greatest discoveries of our time is that a man can alter the state of their life by altering the state of their mind.

We are all ready to be savage in some cause. The difference between a good man and a bad one is the choice of the cause.

We [may] answer the question: "Why is snow white?" by saying, "For the same reason that soap-suds or whipped eggs are white"-in other words, instead of giving the reason for a fact, we give another example of the same fact. This offering a similar instance, instead of a reason, has often been criticised as one of the forms of logical depravity in men. But manifestly it is not a perverse act of thought, but only an incomplete one. Furnishing parallel cases is the necessary first step towards abstracting the reason imbedded in them all.

Between what a man calls me and what he simply calls mine the line is difficult to draw. We feel and act about certain things that are ours very much as we feel and act about ourselves.

The intellectual life of man consists almost wholly in his substitution of conceptual order for the perceptual order in which his experience originally comes.
