Robert Louis Stevenson on Knowledge

"There are circumstances in which even the least energetic of mankind learn to behave with vigour and decision; and the most cautious forget their prudence and embrace foolhardy resolutions."

"It is one thing to mortify curiosity, another to conquer it."

"There is certainly some chill and arid knowledge to be found upon the summits of formal and laborious science; but it is all round about you, and for the trouble of looking, that you will acquire the warm and palpitating facts of life."

"Age may have one side, but assuredly Youth has the other. There is nothing more certain than that both are right, except perhaps that both are wrong. Let them agree to differ; for who knows but what agreeing to differ may not be a form of agreement rather than a form of difference?"

"Doctors is all swabs... and that doctor there, why, what do he know about seafaring men? I been in places hot as pitch, and mates dropping round with Yellow Jack, and the blessed land a-heaving like the sea with earthquakes — what do the doctor know of lands like that? — and I lived on rum, I tell you."

"Hope is the boy, a blind, headlong, pleasant fellow, good to chase swallows with the salt; Faith is the grave, experienced, yet smiling man. Hope lives on ignorance; open-eyed Faith is built upon a knowledge of our life, of the tyranny of circumstance and the frailty of human resolution. Hope looks for unqualified success; but Faith counts certainly on failure, and takes honourable defeat to be a form of victory. Hope is a kind old pagan; but Faith grew up in Christian days, and early learnt humility. In the one temper, a man is indignant that he cannot spring up in a clap to heights of elegance and virtue; in the other, out of a sense of his infirmities, he is filled with confidence because a year has come and gone, and he has still preserved some rags of honour. In the first, he expects an angel for a wife; in the last, he knows that she is like himself - erring, thoughtless, and untrue; but like himself also, filled with a struggling radiancy of better things, and adorned with ineffective qualities. You may safely go to school with hope; but ere you marry, should have learned the mingled lesson of the world: that dolls are stuffed with sawdust, and yet are excellent play-things; that hope and love address themselves to a perfection never realised, and yet, firmly held, become the salt and staff of life; that you yourself are compacted of infirmities, perfect, you might say, in imperfection, and yet you have a something in you lovable and worth preserving; and that, while the mass of mankind lies under this scurvy condemnation, you will scarce find one but, by some generous reading, will become to you a lesson, a model, and a noble spouse through life."
