[Ch 3, 4] Logic and Proofs (2) 1. Valid and Invalid Arguments (§2.3
... After an argument is determined to be valid, we can construct a proof. But before we proceed to proofs, we must remember that • Validity of an argument is only about the form (e.g. Modus Ponens), and NOT about the content. e.g. If 2 = 3, then I ate my hat. I ate my hat. ...

Removing that idea directly leads to undermining the outlook which sees CH as a problem to do with continua, since if there is no number of points in some stuff then there is no question of whether that number is, or is not greater than some other ...

NOTES ON LOGIC 1913
... When we say A judges that etc., then we have to mention a whole proposition which A judges. It will not do either to mention only its constituents, or its constituents and form, but not in the proper order. This shows that a proposition itself must occur in the statement that it is judged; however, ...
