Problem: Idealism:

Idealism is a term with several related meanings. It comes via idea from the Greek idein (ἰδεῖν), meaning "to see". The term entered the English language by 1743. In ordinary use, as when speaking of Woodrow Wilson's political idealism, it generally suggests the priority of ideals, principles, values, and goals over concrete realities. Idealists are understood to represent the world as it might or should be, unlike pragmatists, who focus on the world as it presently is. In the arts, similarly, idealism affirms imagination and attempts to realize a mental conception of beauty, a standard of perfection, juxtaposed to aesthetic naturalism and realism.

By what year was "idealism" a word in English?

A: 1743

Q: What is a question about this article? If the question is unanswerable, say "unanswerable".
The textual critic's ultimate objective is the production of a "critical edition".[citation needed] This contains the text that the author has determined most closely approximates the original, and is accompanied by an apparatus criticus or critical apparatus. The critical apparatus presents the author's work in three parts: first, a list or description of the evidence that the editor used (names of manuscripts, or abbreviations called sigla); second, the editor's analysis of that evidence (sometimes a simple likelihood rating),[citation needed]; and third, a record of rejected variants of the text (often in order of preference).[citation needed]
What is the purpose of the rejected apparatus?
A: unanswerable


Context and question: In the classical case, the invariance, or symmetry, group and the covariance group coincide, but, interestingly enough, they part ways in relativistic physics. The symmetry group of the general theory of relativity includes all differentiable transformations, i.e., all properties of an object are dynamical, in other words there are no absolute objects. The formulations of the general theory of relativity, unlike those of classical mechanics, do not share a standard, i.e., there is no single formulation paired with transformations. As such the covariance group of the general theory of relativity is just the covariance group of every theory.
What theory does relativity coincide with?
Answer: unanswerable
