Any defense of common sense must allow that it is revisable.

In order to qualify as a judgment, an affirmation must aim at getting it right aptly, through competence, and not just through a lucky guess.

Attempts are found in domains of human performance, such as sports, games, artistic domains, professional domains like medicine and the law, and so on. These feature distinctive aims, and corresponding competences. Archery, with its distinctive arrows and targets, divides into subdomains. Thus, competitive archery differs importantly from archery hunting.

In competitive archery, risk assessment has minimal bearing on quality of performance, since the archer has so little choice over shot selection. By contrast, in a hunt, shots vary in quality according to how well selected they may be.

Any defense of common sense must allow that it is revisable.

There is no need for the scientist to go into whether an observation was made, nor into the who, what, when, or where. The data on which scientific theorizing is based are rather the propositional contents of the instrument readings recorded, or the facts detected thereby.

Epistemology now flourishes with various complementary approaches. This includes formal epistemology, experimental philosophy, cognitive science and psychology, including relevant brain science, and other philosophical subfields, such as metaphysics, action theory, language, and mind. It is not as though all questions of armchair, traditional epistemology are already settled conclusively, with unanimity or even consensus. We still need to reason our way together to a better view of those issues.
