Page 21 - ... values severally and individually. If this were not the case, no function could be apprehended at all, since the number of values (true and false) of a function is necessarily infinite and there are necessarily possible arguments with which we are unacquainted. What is necessary is not that the values should be given individually and extensionally, but that the totality of the values should be given intensionally, so that, concerning any assigned object, it is at least theoretically determinate...
Page 8 - Ponatur quod Socrates dicat illam, "Plato dicit falsum" et Plato dicat illam, "Socrates dicit verum.
Page 10 - This method of dealing with the problem appealed to a number of later writers, Johannis Majoris Scotus, Olkot, and Rosetus among them. It is much the same as Russell's device of the theory of types which depends on the principle of the vicious circle, namely that no term in a proposition can presuppose the proposition or have it as one of its possible values. The only Scholastic to make a serious criticism of this view was...
Page 5 - R does not have the relation R to S". Hence, giving the value T to both R and S," T has the relation T to T " is equivalent to " T does not have the relation T to T".

Page 15 - I am lying", we must interpret him as meaning : "There is a proposition of order n which I affirm and which is false". This is a proposition of order n + 1 ; hence the man is not affirming any proposition of order n ; hence his statement is false, and yet its falsehood does not imply, as that of "I am lying" appeared to do, that he is making a true statement.
Page 8 - ... the last makes its own truth imply the falsity of a class of propositions to which it itself belongs, as does "All propositions are false.
Page 15 - The principle that the more widely distributed traits are the older is correct if properly used, he says, but it must not be used incorrectly. This seems to be equivalent to stating that it is true when it is true, and false when it is false, but gives us no inkling of when it is true and when it is false.
Page 9 - We are given to understand that though the form of our words may seem to refer to itself, nevertheless the thought that leads to the expression never has that character, but always refers to some object independent of it. The rule for avoiding the paradoxes becomes, "Pars propositions non potest supponere...
