On that conception of logical equivalence, (C) is false, and Taylor buys (A).
Both the intuitionistic view of logic as essentially sterile, and the existence of results in intuitionistic logic that are incompatible with classical logic, depend essentially on that conception.
Some have argued that such reflection principles are intrinsically justified on the basis of the iterative conception of set and, moreover, that they exhaust the principles that can be intrinsically justified on that conception (see, for example, Tait (2001), reprinted in (2005b), pp. 283 284).
Pace Hacking, Khalidi (2010) argues that in fact the contrast between natural and social kinds is not so stark: even many chemical kinds would not have been instantiated in the world were it not for the fact that a scientist conceived of it and acted on that conception.
In 1902, Olga suffered a miscarriage; and Donald Rayfield has offered evidence, based on the couple's letters, that conception may have occurred when Chekhov and Olga were apart, although Russian scholars have rejected that claim.
The test is based on the conception that, the equipment, electronics, analytical operations, and samples to be analyzed represent an integral system that can be evaluated.
David Copp (2008), for example, has argued that on the conception of moral truths implied by his society-centered moral naturalism, it is plausible to suppose that a moral psychology shaped by natural selection in social contexts would yield moral beliefs that track moral truths at least reasonably well as a first approximation.
His Summa doctrinae de foedere et testamento Dei (1648; "Comprehensive Treatise on the Doctrines of the Covenant and Testament of God") is based on the conception that the relation between God and man, both before the Fall and after it, was a covenant.
It is easy enough to see that on this conception, ethical egoism is an agent-relative theory (and hence concerns agent-relative reasons) while objective utilitarianism is an agent-neutral theory (and hence concerns agent-neutral reasons).
The parallel flow model or sum of exponential model is based on the conception that when a horizontal well is hydraulically fractured, the reservoir rock is broken and subdivided into discrete blocks, each of which makes independent flow contribution to the fractures.
Note that on this conception of institutions as embodied structures of roles and associated rules, the nature of any institution at a given time will to some extent reflect the personal character of different role occupants, especially influential role occupants, e.g. the British Government during the Second World War reflected to some extent Winston Churchill's character.
