Unprofitable Quotes (7 quotes)
…this discussion would be unprofitable if it did not lead us to appreciate the wisdom of our Creator, and the wondrous knowledge of the Author of the world, Who in the beginning created the world out of nothing, and set everything in number, measure and weight, and then, in time and the age of man, formulated a science which reveals fresh wonders the more we study it.
— Hrosvita
From her play Sapientia, as quoted and cited in Philip Davis with Reuben Hersh, in The Mathematical Experience (1981), 110-111. Davis and Hersh introduce the quote saying it comes “after a rather long and sophisticated discussion of certain facts in the theory of numbers” by the character Sapientia.
Be very vigilent over thy Childe … If he chuse the profession of a Scholler, advise him to study the most profitable Arts: Poetry, and the Mathematichs, take up too great a latitude of the Soule, and moderately used, are good Recreations, but bad Callings, bring nothing but their owne Reward.
From Alexander B. Grosart (ed), 'Enchyridion: The Fourth Book' (1641), The Complete Works in Prose and Verse of Francis Quarles (1880), Vol. 1, 48, Cap. XCIX.
Dreaming over a subject is simply … allowing the will to focus the mind passively on the subject so that it follows the trains of thought as they arise, stopping them only when unprofitable but in general allowing them to form and branch naturally until some useful and interesting results occur.
In An Anatomy of Inspiration (1940), 5.
It may not always be profitable at first for businesses to be online, but it is certainly going to be unprofitable not to be online.

The discovery of the conic sections, attributed to Plato, first threw open the higher species of form to the contemplation of geometers. But for this discovery, which was probably regarded in Plato’s tune and long after him, as the unprofitable amusement of a speculative brain, the whole course of practical philosophy of the present day, of the science of astronomy, of the theory of projectiles, of the art of navigation, might have run in a different channel; and the greatest discovery that has ever been made in the history of the world, the law of universal gravitation, with its innumerable direct and indirect consequences and applications to every department of human research and industry, might never to this hour have been elicited.
In 'A Probationary Lecture on Geometry, Collected Mathematical Papers, Vol. 2 (1908), 7.
The mathematic, then, is an art. As such it has its styles and style periods. It is not, as the layman and the philosopher (who is in this matter a layman too) imagine, substantially unalterable, but subject like every art to unnoticed changes form epoch to epoch. The development of the great arts ought never to be treated without an (assuredly not unprofitable) side-glance at contemporary mathematics.
In Oswald Spengler and Charles Francis Atkinson (trans.), The Decline of the West (1926), 62.
The study of mathematics is, if an unprofitable, a perfectly harmless and innocent occupation.
From Inaugural Lecture, Oxford (1920). Recalled in A Mathematician’s Apology (1940, 1967), 74.
In science it often happens that scientists say, 'You know that's a really good argument; my position is mistaken,' and then they would actually change their minds and you never hear that old view from them again. They really do it. It doesn't happen as often as it should, because scientists are human and change is sometimes painful. But it happens every day. I cannot recall the last time something like that happened in politics or religion.
(1987) --
