ABSTRACT
This chapter attempts a similar task with regard to the predicate True. Generalization of the subject of a proposition rests upon some such postulate as that of the so-called 'Uniformity of Nature' is a commonplace. The Theory of Relativity is essentially a proposition concerning the physical world, and it is made such by introducing the supposition that the quantities entering into the statement of the Principle represent measurements. The liberalistic position thus involves that if any man is to be brought to a conviction of errors. To remove the ambiguity, one more convention is needed, which will specify the particular observer whose intuition is finally to define the sameness or difference of the weights. Sometimes indeed, more than one point is at issue at once; but what people then have is really not one but several doubtful propositions, with some common datum and diverse dubitatum.
