Datum Quotes (3 quotes)
Knowledge is invariably a matter of degree: you cannot put your finger upon even the simplest datum and say “this we know.”
From Knowledge and Experience in the Philosophy of F.H. Bradley (1964, 1989), 151.
The supreme goal of all theory is to make the irreducible basic elements as simple and as few as possible without having to surrender the adequate representation of a single datum of experience.

When a man of science speaks of his “data,” he knows very well in practice what he means. Certain experiments have been conducted, and have yielded certain observed results, which have been recorded. But when we try to define a “datum” theoretically, the task is not altogether easy. A datum, obviously, must be a fact known by perception.

In The Analysis of Matter (1954).
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.

I cannot recall the last time something like that happened in politics or religion.
