Ahhh what a brilliant man he was!!! One of my favorite quotations:
"There is only one difference between a bad economist and a good one: the bad economist confines himself to the visible effect; the good economist takes into account both the effect that can be seen and those effects that must be foreseen.
Yet this difference is tremendous; for it almost always happens that when the immediate consequence is favorable, the later consequences are disastrous, and vice versa. Whence it follows that the bad economist pursues a small present good that will be followed by a great evil to come, while the good economist pursues a great good to come, at the risk of a small present evil.
The same thing, of course, is true of health and morals. Often, the sweeter the first fruit of a habit, the more bitter are its later fruits: for example, debauchery, sloth, prodigality. When a man is impressed by the effect that is seen and has not yet learned to discern the effects that are not seen, he indulges in deplorable habits, not only through natural inclination, but deliberately.
This explains man's necessarily painful evolution. Ignorance surrounds him at his cradle; therefore, he regulates his acts according to their first consequences, the only ones that, in his infancy, he can see. It is only after a long time that he learns to take account of the others."
