“Learning is its own exceeding great reward; and at the period of which we speak, it bore other fruits, not unworthy of it.”

Lecture notes of 1858, quoted in The Life and Letters of Faraday (1870) by Bence Jones, Vol. 2, p. 403
Context: We learn by such results as these, what is the kind of education that science offers to man. It teaches us to be neglectful of nothing, not to despise the small beginnings — they precede of necessity all great things. Vesicles make clouds; they are trifles light as air, but then they make drops, and drops make showers, rain makes torrents and rivers, and these can alter the face of a country, and even keep the ocean to its proper fulness and use. It teaches a continual comparison of the small and great, and that under differences almost approaching the infinite, for the small as often contains the great in principle, as the great does the small; and thus the mind becomes comprehensive. It teaches to deduce principles carefully, to hold them firmly, or to suspend the judgment, to discover and obey law, and by it to be bold in applying to the greatest what we know of the smallest. It teaches us first by tutors and books, to learn that which is already known to others, and then by the light and methods which belong to science to learn for ourselves and for others; so making a fruitful return to man in the future for that which we have obtained from the men of the past.

Context: When I was young I longed to write a great novel that should win me fame. Now that I am getting old my first book is written to amuse children. For aside from my evident inability to do anything "great," I have learned to regard fame as a will-o-the-wisp which, when caught, is not worth the possession; but to please a child is a sweet and lovely thing that warms one's heart and brings its own reward.

Context: I cannot call this Shakspeare a "Sceptic," as some do; his indifference to the creeds and theological quarrels of his time misleading them. No: neither unpatriotic, though he says little about his Patriotism; nor sceptic, though he says little about his Faith. Such "indifference" was the fruit of his greatness withal: his whole heart was in his own grand sphere of worship (we may call it such); these other controversies, vitally important to other men, were not vital to him.
