In this article we will explain and defend the proposition: “A statement which prescribes (entails) the conditions for its verification is a scientific statement.” We will confine our consideration to factual (synthetic) statements alone, although it may be true that our proposed proposition refers to formal, analytic statements also.
If prescribing the conditions for its verification is the only necessary qualification for a statement to be scientific then obviously the means of arriving at such a statement is irrelevant. It does not matter whether we have performed many experiments or none before making a scientific statement. There are, of course, reasons for having a systematic method of arriving at the formulation of scientific statements, but this does not make them more, or less, scientific.
1 For a clear expression of the view that the meaning of a factual statement is identical with the means of verifying it, see Boas and Blumberg, “Some Remarks in Defense of the Operational Theory of Meaning,” Jour. of Philos., XXVIII (1931); Blumberg and Feigl, “Logical Positivism,” Jour. of Philos., XXVIII (1931). In “Logical Positivism,” we find, “To know the meaning of a proposition is to know what must be the case if the proposition is true.”
2 For an excellent recent criticism of this view see “Are all Empirical Statements Merely Hypotheses?”, by W. T. Stace, in Jour. of Philos., vol. XLIV, No. 2.
