“The sweetest and most inoffensive path of life leads through the avenues of science and learning; and whoever can either remove any obstructions in this way, or open up any new prospect, ought so far to be esteemed a benefactor to mankind. And though these researches may appear painful and fatiguing. It is with some minds as with some bodies, which being endowed with vigorous and florid health, require severe exercise, and reap a pleasure from what, to the generality of mankind, may seem burdensome and laborious. Obscurity, indeed, is painful to the mind as well as to the eye; but to bring light from obscurity, by whatever labour, must needs be delightful and rejoicing.”

“Philosophy, for Plato, is a kind of vision, the 'vision of truth' ... Everyone who has done any kind of creative work has experienced, in a greater or less degree, the state of mind in which, after long labour, truth or beauty appears, or seems to appear, in a sudden glory – it may only be about some small matter, or it may be about the universe ... I think most of the best creative work, in art, in science, in literature, and in philosophy, has been the result of such a moment.”

“Whatever is fitted in any sort to excite the ideas of pain, and danger, that is to say, whatever is in any sort terrible, or is conversant about terrible objects, or operates in a manner analogous to terror, is a source of the sublime; that is, it is productive of the strongest emotion which the mind is capable of feeling .... When danger or pain press too nearly, they are incapable of giving any delight, and [yet] with certain modifications, they may be, and they are delightful, as we every day experience.”

“It is a good principle in science not to believe any 'fact'---however well attested---until it fits into some accepted frame of reference. Occasionally, of course, an observation can shatter the frame and force the construction of a new one, but that is extremely rare. Galileos and Einsteins seldom appear more than once per century, which is just as well for the equanimity of mankind.”

“Ingratitude is amongst them a capital crime, as we read it to have been in some other countries: for they reason thus; that whoever makes ill-returns to his benefactor, must needs be a common enemy to the rest of the mankind, from where he has received no obligations and therefore such man is not fit to live.”

“I have very carefully studied Islam and the life of its Prophet (PBUH). I have done so both as a student of history and as a critic. And I have come to conclusion that Muhammad (PBUH) was indeed a great man and a deliverer and benefactor of mankind which was till then writhing under the most agonising Pain.”
