I
agree that our methods of control are unlikely to be sufficiently
delicate or sufficiently powerful to maintain continuous full
employment. I should be quite content with a reasonable
**approximation** to it, and in practice I should probably
relax my expansionist measures a little before technical
full employment had actually been reached.

An artist cannot be partially sincere any more than art can be an **approximation** of beauty.

“To stamp becoming with the character of being that is the supreme will to power.” (WM 617) This suggests that becoming only is if it is grounded in being as being: “That everything recurs is the closest **approximation** of a world of becoming to one of being.”

— p. 19 (Nietzsche (1961))

Each such answer to the great question, invariably asserted by the followers of its propounder, if not by himself, to be complete and final, remains in high authority and esteem, it may be for one century, or it may be for twenty: but, as invariably, Time proves each reply to have been a mere **approximation** to the truth tolerable chiefly on account of the ignorance of those by whom it was accepted, and wholly intolerable when tested by the larger knowledge of their successors.

Mr. Darwin's hypothesis is not, so far as I am aware, inconsistent with any known biological fact; on the contrary, if admitted, the facts of Development, of Comparative Anatomy, of Geographical Distribution, and of Palaeontology, become connected together, and exhibit a meaning such as they never possessed before; and I, for one, am fully convinced that if not precisely true, that hypothesis is as near an **approximation** to the truth as, for example, the Copernican hypothesis was to the true theory of the planetary motions.

The capacity of the human mind for formulating and solving complex problems is very small compared with the size of the problems whose solution is required for objectively rational behavior in the real world or even for a reasonable **approximation** to such objective rationality.

— Herbert Simon (1957)

The principle of bounded rationality [is] the capacity of the human mind for formulating and solving complex problems is very small compared with the size of the problems whose solution is required for objectively rational behavior in the real world or even for a reasonable **approximation** to such objective rationality.

In geometry his greatest achievement was an accurate value of ?. His rule is stated as: dn^2+(2a-d)n=2s, which implies the **approximation** 3.1416 which is correct to the last decimal place.

To a good **approximation**, all species are insects.

— Robert May, quoted in Richard Dawkins,

The societal division of labor obtains the dignity of an ontological condition. If truth presupposes freedom from toil, and if this freedom is, in the social reality, the prerogative of a minority, then the reality allows such a truth only in **approximation** and for a privileged group.

— Herbert Marcuse (1964),

Let us suppose that we have set the problem of finding a solution to the equation This is a problem for which the Babylonians around 1700 BC found the excellent **approximation** ...This is the identical problem which Pythagoras asserted had no fractional solution and in whose honor he was supposed to have sacrificed a hecatomb of oxen the problem which caused the existentialist crisis in ancient Greek mathematics. The exists (as the diagonal of the unit square); yet it does not exist (as a fraction)!

nocturnal monsters that threaten to invade my waking life.
