“A linguistic system is a series of differences of sound combined with a series of differences of ideas; but the pairing of a certain number of acoustical signs with as many cuts made from the mass of thought engenders a system of values.”

The Principles of Success in Literature (1865)
Context: In the development of the great series of animal organisms, the Nervous System assumes more and more of an imperial character. The rank held by any animal is determined by this character, and not at all by its bulk, its strength, or even its utility. In like manner, in the development of the social organism, as the life of nations becomes more complex, Thought assumes a more imperial character; and Literature, in its widest sense, becomes a delicate index of social evolution. Barbarous societies show only the germs of literary life. But advancing civilisation, bringing with it increased conquest over material agencies, disengages the mind from the pressure of immediate wants, and the loosened energy finds in leisure both the demand and the means of a new activity: the demand, because long unoccupied hours have to be rescued from the weariness of inaction; the means, because this call upon the energies nourishes a greater ambition and furnishes a wider arena.
