I wonder what especial sanctity attaches itself to fifteen minutes. It is always the maximum and the minimum of time which will enable us to acquire languages, etiquette, personality, oratory ... One gathers that twelve minutes a day would be hopelessly inadequate, and twenty minutes a wasteful and ridiculous excess.
In science it often happens that scientists say, 'You know that's a really good argument; my position is mistaken,' and then they would actually change their minds and you never hear that old view from them again. They really do it. It doesn't happen as often as it should, because scientists are human and change is sometimes painful. But it happens every day. I cannot recall the last time something like that happened in politics or religion.
Schools have not necessarily much to do with education...they are mainly institutions of control where certain basic habits must be inculcated in the young. Education is quite different and has little place in school.
The last few decades have been marked by a special cultivation of the romance of the future. We seem to have made up our minds to misunderstand what has happened; and we turn, with a sort of relief, to stating what will happen-which is apparently much easier...The modern mind is forced towards the future by a certain sense of fatigue, not unmixed with terror, with which it regards the past.
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.
