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.

Poetry and the Age (1953)
Context: People always ask: For whom does the poet write? He needs only to answer, For whom do you do good? Are you kind to your daughter because in the end someone will pay you for being?... The poet writes his poem for its own sake, for the sake of that order of things in which the poem takes the place that has awaited it.
