Definition of "confirmability"

Nothing seems more natural than to approach confirmability via confirmation.

1968, G. Schlesinger, “Confirmability and Determinism,”, in The Philosophical Quarterly, volume 18, number 70, page 30

So the confirmability as well as the refutability of our theories (conditional if not categorical) are necessary conditions for the possibility of science.
