Things may come to those who wait, but only the things left by those who hustle. - Abraham Lincoln

A capacity, and taste, for reading, gives access to whatever has already been discovered by others. It is the key, or one of the keys, to the already solved problems. And not only so. It gives a relish, and facility, for successfully pursuing the [yet] unsolved ones.

You dislike the emancipation proclamation; and, perhaps, would have it retracted. You say it is unconstitutional — I think differently. I think the constitution invests its commander-in-chief, with the law of war, in time of war. The most that can be said, if so much, is, that slaves are property. Is there — has there ever been — any question that by the law of war, property, both of enemies and friends, may be taken when needed? And is it not needed whenever taking it, helps us, or hurts the enemy? Armies, the world over, destroy enemies' property when they can not use it; and even destroy their own to keep it from the enemy. Civilized belligerents do all in their power to help themselves, or hurt the enemy, except a few things regarded as barbarous or cruel. Among the exceptions are the massacre of vanquished foes, and non-combatants, male and female.

Look at the magnitude of this subject! One sixth of our population, in round numbers — not quite one sixth, and yet more than a seventh, — about one sixth of the whole population of the United States are slaves! The owners of these slaves consider them property. The effect upon the minds of the owners is that of property, and nothing else — it induces them to insist upon all that will favorably affect its value as property, to demand laws and institutions and a public policy that shall increase and secure its value, and make it durable, lasting and universal. The effect on the minds of the owners is to persuade them that there is no wrong in it. The slaveholder does not like to be considered a mean fellow, for holding that species of property, and hence he has to struggle within himself and sets about arguing himself into the belief that Slavery is right. The property influences his mind. [...] Certain it is, that this two thousand million of dollars, invested in this species of property, all so concentrated that the mind can grasp it at once — this immense pecuniary interest, has its influence upon their minds.
