“You have an interesting history. Now people can generally be classified in to two groups: the mediocre realists and the mediocre dreamers. You clearly belong to the letter. Your fate is and will always be the fate of dreamers.”

Crabbed Age and Youth.
Virginibus Puerisque and Other Papers (1881)
Context: There is a strong feeling in favour of cowardly and prudential proverbs. The sentiments of a man while he is full of ardour and hope are to be received, it is supposed, with some qualification. But when the same person has ignominiously failed and begins to eat up his words, he should be listened to like an oracle. Most of our pocket wisdom is conceived for the use of mediocre people, to discourage them from ambitious attempts, and generally console them in their mediocrity. And since mediocre people constitute the bulk of humanity, this is no doubt very properly so. But it does not follow that the one sort of proposition is any less true than the other, or that Icarus is not to be more praised, and perhaps more envied, than Mr. Samuel Budgett the Successful Merchant. The one is dead, to be sure, while the other is still in his counting-house counting out his money; and doubtless this is a consideration. But we have, on the other hand, some bold and magnanimous sayings common to high races and natures, which set forth the advantage of the losing side, and proclaim it better to be a dead lion than a living dog. It is difficult to fancy how the mediocrities reconcile such sayings with their proverbs. According to the latter, every lad who goes to sea is an egregious ass; never to forget your umbrella through a long life would seem a higher and wiser flight of achievement than to go smiling to the stake; and so long as you are a bit of a coward and inflexible in money matters, you fulfil the whole duty of man.

Preface.
A History of Science Vol.1 Ancient Science Through the Golden Age of Greece (1952)
Context: Some men are abstract-minded, and they naturally think first of unity and God, of wholeness, of infinity and other such concepts, while the minds of other men are concrete and they cogitate about health and disease, profit and loss. They invent gadgets and remedies; they are less interested in knowing anything than in applying whatever knowledge... to practical problems... The first are called dreamers; the second kind are recognized as practical and useful. History has often proved the shortsightedness of the practical men and vindicated the "lazy" dreamers; it has also proved that the dreamers are often mistaken.
