„Pure mathematics is in its way the poetry of logical ideas.“

1930s, Obituary for Emmy Noether (1935)
Contexto: Pure mathematics is, in its way, the poetry of logical ideas. One seeks the most general ideas of operation which will bring together in simple, logical and unified form the largest possible circle of formal relationships. In this effort toward logical beauty spiritual formulas are discovered necessary for the deeper penetration into the laws of nature.

„There is a logic of language and a logic of mathematics.“

—  Thomas Merton Priest and author 1915 - 1968

Contexto: There is a logic of language and a logic of mathematics. The former is supple and lifelike, it follows our experience. The latter is abstract and rigid, more ideal. The latter is perfectly necessary, perfectly reliable: the former is only sometimes reliable and hardly ever systematic. But the logic of mathematics achieves necessity at the expense of living truth, it is less real than the other, although more certain. It achieves certainty by a flight from the concrete into abstraction. Doubtless, to an idealist, this would seem to be a more perfect reality. I am not an idealist. The logic of the poet — that is, the logic of language or the experience itself — develops the way a living organism grows: it spreads out towards what it loves, and is heliotropic, like a plant.

„Common Logic is the Grammar of the higher Speech, that is, of Thought; it examines merely the relations of ideas to one another, the Mechanics of Thought, the pure Physiology of ideas. Now logical ideas stand related to one another, like words without thoughts. Logic occupies itself with the mere dead Body of the Science of Thinking.“

—  Novalis German poet and writer 1772 - 1801

Metaphysics, again, is the Dynamics of Thought; treats of the primary Powers of Thought; occupies itself with the mere Soul of the Science of Thinking. Metaphysical ideas stand related to one another, like thoughts without words. Men often wondered at the stubborn Incompletibility of these two Sciences; each followed its own business by itself; there was a want everywhere, nothing would suit rightly with either. From the very first, attempts were made to unite them, as everything about them indicated relationship; but every attempt failed; the one or the other Science still suffered in these attempts, and lost its essential character. We had to abide by metaphysical Logic, and logical Metaphysic, but neither of them was as it should be.

The Scientific Outlook (1931)
Contexto: Ordinary language is totally unsuited for expressing what physics really asserts, since the words of everyday life are not sufficiently abstract. Only mathematics and mathematical logic can say as little as the physicist means to say.

„A poetry of revolt against moral ideas is a poetry of revolt against life; a poetry of indifference towards moral ideas is a poetry of indifference towards life.“

—  Matthew Arnold English poet and cultural critic who worked as an inspector of schools 1822 - 1888

Wordsworth, originally published as "Preface to the Poems of Wordsworth" in Macmillan's Magazine (July 1879)
Essays in Criticism, second series (1888)
Contexto: If what distinguishes the greatest poets is their powerful and profound application of ideas to life, which surely no good critic will deny, then to prefix to the word ideas here the term moral makes hardly any difference, because human life itself is in so preponderating a degree moral.
It is important, therefore, to hold fast to this: that poetry is at bottom a criticism of life; that the greatness of a poet lies in his powerful and beautiful application of ideas to life — to the question, How to live. Morals are often treated in a narrow and false fashion, they are bound up with systems of thought and belief which have had their day, they are fallen into the hands of pedants and professional dealers, they grow tiresome to some of us. We find attraction, at times, even in a poetry of revolt against them; in a poetry which might take for its motto Omar Khayam's words: "Let us make up in the tavern for the time which we have wasted in the mosque." Or we find attractions in a poetry indifferent to them, in a poetry where the contents may be what they will, but where the form is studied and exquisite. We delude ourselves in either case; and the best cure for our delusion is to let our minds rest upon that great and inexhaustible word life, until we learn to enter into its meaning. A poetry of revolt against moral ideas is a poetry of revolt against life; a poetry of indifference towards moral ideas is a poetry of indifference towards life.
