To know how little one knows is to have genuine knowledge. Not to know how little one knows is to be deluded. Only those who know when they are deluded can free themselves from such delusion. The intelligent people are not deluded, because they know and accept their ignorance as ignorance, and thereby have genuine knowledge.
Aristocracy's only an admission that certain traits which we call fine - courage and honor and beauty and all that sort of thing - can best be developed in a favorable environment, where you don't have the warpings of ignorance and necessity.
Because past environmental destruction was the result of ignorance, we can easily forgive it. Today, we are better informed. Therefore, it's essential that we make an ethical examination of what we have inherited, what we are responsible for, and what we will pass on to coming generations. Ours is clearly a pivotal generation. We have global communication and yet confrontation is more common than dialogue.
The greater the scientist, the more he is impressed with his ignorance of reality, and the more he realizes that his laws and labels, descriptions and definitions, are the products of his own thought. They help him to use the world for purposes of his own devising rather than understand and explain it.
It is a mischievous notion that we are come late into nature; that the world was finished a long time ago. As the world was plastic and fluid in the hands of God, so it is ever to so much of his attributes as we bring to it. To ignorance and sin, it is flint. They adapt to themselves to it as they may; but in proportion as a man has anything in him divine, the firmament flows before him and takes his signet and form.
Exploitation of the poor can be extinguished not by effecting the destruction of a few millionaires, but by removing the ignorance of the poor and teaching them to non-cooperate with their exploiters.
The things best to know are first principles and causes, but these things are perhaps the most difficult for men to grasp, for they are farthest removed from the senses.
Facts or opinions which are to pass through the hands of so many, to be misconceived by folly in one, and ignorance in another, can hardly have much truth left.
