We must know, if only in order to learn not to know. The supreme lesson of human consciousness is to learn how not to know. That is, how not to interfere.
It is the inefficiency and sham of ... our schools ... that save us from being dashed on the rocks of false doctrine instead of drifting down the midstream of mere ignorance.
Hostile armies may face each other for years, striving for the victory which is decided in a single day. This being so, to remain in ignorance of the enemy's condition simply because one grudges the outlay of a hundred ounces of silver in honors and emoluments, is the height of inhumanity.
It belongs to small-mindedness to be unable to bear either honor or dishonor, either good fortune or bad, but to be filled with conceit when honored and puffed up by trifling good fortune, and to be unable to bear even the smallest dishonor and to deem any chance failure a great misfortune, and to be distressed and annonyed at everything. Moreover the small-minded man is the sort of person to call all slights an insult and dishonor, even those that are due to ignorance or forgetfulness. Small-mindedness is accompanied by pettiness, querulousness, pessimism and self-abasement.
The ground for taking ignorance to be restrictive of freedom is that it causes people to make choices which they would not have made if they had seen what the realization of their choices involved.
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.
I should have liked to be asked to say what I knew. They always tried to ask what I did not know. When I would have willingly displayed my knowledge, they sought to expose my ignorance. This sort of treatment had only one result: I did not do well in examinations
I have heard of your paintings too, well enough; God has given you one face, and you make yourselves another: you jig, you amble, and you lisp, and nick-name God's creatures, and make your wantonness your ignorance. Go to, I'll no more on't; it hath made me mad.
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.
It is an unfortunate fact that every man who seeks to disseminate knowledge must contend not only against ignorance itself, but against false instruction as well. No sooner do we deem ourselves free from a particularly gross superstition, than we are confronted by some enemy to learning who would set aside all the intellectual progress of years, and plunge us back into the darkness of mediaeval disbelief.
Who can tell whether the parallelogram, which in our ignorance we have defined and drawn, and the whole of whose properties we profess to know, may not be all the while panting for exterior angles, sympathetic with the interior, or sullenly repining at the fact that it cannot be inscribed in a circle?
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.
