Education is the instruction of the intellect in the laws of Nature, under which name I include not merely things and their forces, but people and their ways; and the fashioning of the affections and of the will into an earnest and loving desire to move in harmony with those laws.

And you very soon find out, if you have not found it out before, that patience and tenacity of purpose are worth more than twice their weight of cleverness.

The thief and the murderer follow nature just as much as the philanthropist.

As I have already urged, the practice of that which is ethically best - what we call goodness or virtue - involves a course of conduct which, in all respects, is opposed to that which leads to success in the cosmic struggle for existence. In place of ruthless selfassertion it demands self-restraint; in place of thrusting aside, or treading down, all competitors, it requires that the individual shall not merely respect , but shall help his fellows. It repudiates the gladiatorial theory of existence. Laws and moral precepts are directed to the end of curbing the cosmic process.

The besetting sin of able men is impatience of contradiction and of criticism.
