I do not need to have a control group, a placebo or a degree to be an applicator of knowledge.

I have my results. They have their textbooks.

The unfortunate thing about experts is that they are afraid to be wrong.

Suppose that we are wise enough to learn and know - and yet not wise enough to control our learning and knowledge, so that we use it to destroy ourselves? Even if that is so, knowledge remains better than ignorance.

to learn and not to do is really not to learn. To know and not to do is really not to know.

Confusion: You cannot speak of your achievements for you are conceited, yet you cannot speak of wrongs because you complain. We encourage you to learn, yet if you teach what you learnt you are not qualified. You may be ridiculed for never taking chances in life, but if you do you must be careful. You are allowed to smoke whilst complaining about pollution. We must protect refugees fleeing war, yet we are scorned for protecting them in their homeland.
