Problems may be solved in the study which have baffled all those who have sought a solution by the aid of their senses. To carry the art, however, to its highest pitch, it is necessary that the reasoner should be able to use all the facts which have come to his knowledge; and this in itself implies, as you will readily see, a possession of all knowledge, which, even in these days of free education and encyclopaedias, is a somewhat rare accomplishment.

If you have a 2 or 3 year old who is not talking, you must start an early intervention program. The worst thing you can do with an autistic 3 year old is to do nothing.

Never regard study as a duty, but as the enviable opportunity to learn

I loved everything. I loved sciences and I loved humanities. But ultimately, I felt that in the humanities, you know, you're writing about things that already exist. But in the sciences, you're discovering things that no one has known before. Ultimately I chose psychology because it seemed to combine science with things that I liked to think about.

I believe that of all the things I have done, exciting though many of them have been, there's no doubt in my mind that the most worthwhile have been the establishing of schools and hospitals, and the rebuilding of monasteries in the mountains.
