 But soon afterwards, in his Logical Syntax, and more explicitly when he published “Testability and Meaning” in 1936–37, Carnap decisively distanced himself from such doctrines. In the light of the new principle of tolerance, the obsession with just one standard language form seemed unnecessarily “absolutist” and rigid. In “Testability and Meaning” it is stressed that many different language forms are possible in science and should be investigated, and that none is “correct” or uniquely acceptable for the purposes of scientific confirmation. The point is to devise languages that meet certain goals of inquiry better than others, in the awareness that some languages may be better for the pursuit of one goal, while other languages are preferable for other goals.
