In order to discover whether the picture is true or false we must compare it with reality. It cannot be discovered from the picture alone whether it is true or false. There is no picture which is a priori true.
...mathematics is distinguished from all other sciences except only ethics, in standing in no need of ethics. Every other science, even logic, especially in its early stages, is in danger of evaporating into airy nothingness, degenerating, as the Germans say, into an arachnoid film, spun from the stuff that dreams are made of. There is no such danger for pure mathematics; for that is precisely what mathematics ought to be.
We are beginning to play with ideas of ecology, and although we immediately trivialize these into commerce or politics, there is at least an impulse still in the human breast to unify and thereby sanctify the total natural world, of which we are.... There have been, and still are, in the world many different and even contrasting epistemologies which have been alike in stressing an ultimate unity, and, although this is less sure, which have also stressed the notion that ultimate unity is aesthetic. The uniformity of these views gives hope that perhaps the great authority of quantitative science may be insufficient to deny an ultimate unifying beauty. I hold to the presupposition that our loss of the sense of aesthetic unity was, quite simply, an epistemological mistake.
I think it is always important to ask fundamental questions, but when we do ask a fundamental question, most of us are seeking an answer, and then the answer is invariably superficial because there is no yes or no answer to life. Life is a movement, an endless movement, and to inquire into this extraordinary thing called life, with all its innumerable aspects, one must ask fundamental questions and never be satisfied with answers, however satisfactory they may be, because the moment you have an answer, the mind has concluded, and conclusion is not life - it is merely a static state. So what is important is to ask the right question and never be satisfied with the answer, however clever, however logical, because the truth of the question lies beyond the conclusion, beyond the answer, beyond the verbal expression. The mind that asks a question and is merely satisfied with an explanation, a verbal statement, remains superficial. It is only the mind that asks a fundamental question and is capable of pursuing that question to the end - it is only such a mind that can find out what is truth.
Do not allow your dreams of a beautiful world to lure you away from the claims of men who suffer here and now. Our fellow men have a claim to our help; no generation must be sacrificed for the sake of future generations, for the sake of an ideal of happiness that may never be realised.
It is difficult to think of anything more important than providing the best education possible for our children. They will develop the next technologies, medical cures, and global industries, while mitigating their unintended effects, or they will fail to do these things and consign us all to oblivion.
