1 is wrong. Please try again.

According to Austin, all the truths of math and logic are certain and incorrigible.

Many such truths (especially complex ones like "56 * 78 = 4368") are neither certain nor incorrigible.

Some truths of math and logic are certain to us because they're very firmly established. They aren't certain just because they're about math or logic.
