The ever-recurring law of necessity soon teaches a man to do what he does not like, so as to avert evils which he would dislike still more. Such is the use of foresight, and this foresight, well or ill used, is the source of all the wisdom or the wretchedness of mankind.

Context

“As soon as he has sufficient self-knowledge to understand what constitutes his well-being, as soon as he can grasp such far-reaching relations as to judge what is good for him and what is not, then he is able to discern the difference between work and play, and to consider the latter merely as relaxation. The objects of real utility may be introduced into his studies and may lead him to more prolonged attention than he gave to his games. The ever-recurring law of necessity soon teaches a man to do what he does not like, so as to avert evils which he would dislike still more. Such is the use of foresight, and this foresight, well or ill used, is the source of all the wisdom or the wretchedness of mankind. Every one desires happiness, but to secure it he must know what happiness is. For the natural man happiness is as simple as his life; it consists in the absence of pain; health, freedom, the necessaries of life are its elements.” source
