The error is of an identical style as though cows have been deﬁned as what can be purchased from a cattle-merchant. To someone who knew a number of cattle-merchants, yet had by no means obvious a cow, this may look an admirable deﬁnition. but when in his travels he came upon a herd of untamed cows, he must claim that they weren't cows in any respect, simply because no cattle-merchant may well promote them. So inﬁnite numbers have been declared to not be numbers in any respect, simply because they can no longer be reached by way of counting. will probably be worthy whereas to think about for a second what counting really is. We count number a suite of items once we enable our awareness go from one to a different, until eventually we've got attended as soon as to every, announcing the names of the numbers so as with each one successive act of consciousness. The final quantity named during this strategy is the variety of the gadgets, and for this reason counting is a technique of ﬁnding out what the variety of the items is. yet this operation is known as a very advanced one, and people who think that it's the logical resource of quantity express themselves remarkably incapable of research. within the ﬁrst position, once we say “one, , 3 . . . ” as we count number, we can't be acknowledged to be learning the variety of the items counted until we connect a few desiring to the phrases one, , 3. . . . a baby may well discover ways to be aware of those phrases so as, and to copy them adequately just like the letters of the alphabet, with out attaching any intending to them. the sort of baby could count number accurately from the viewpoint of a grown-up listener, with no need any suggestion of numbers in any respect. The operation of counting, in truth, can simply be intelligently played via a 151 152 clinical strategy in philosophy one who already has a few inspiration what the numbers are; and from this it follows that counting doesn't provide the logical foundation of quantity. back, how can we understand that the final quantity reached within the strategy of counting is the variety of the items counted? this is often only one of these evidence which are too regular for his or her signiﬁcance to be discovered; yet those that desire to be logicians needs to collect the behavior of living upon such proof. There are propositions fascinated by this truth: ﬁrst, that the variety of numbers from 1 as much as any given quantity is that given number—for example, the variety of numbers from 1 to a hundred is 100; secondly, that if a collection of numbers can be utilized as names of a collection of gadgets, every one quantity happening just once, then the variety of numbers used as names is equal to the variety of gadgets. The ﬁrst of those propositions is in a position to a simple arithmetical evidence as long as ﬁnite numbers are involved; yet with inﬁnite numbers, after the ﬁrst, it ceases to be real. the second one proposition is still precise, and is actually, as we will see, a right away final result of the deﬁnition of quantity. yet due to the falsehood of the ﬁrst proposition the place inﬁnite numbers are involved, counting, no matter if it have been virtually attainable, wouldn't be a legitimate approach to getting to know the variety of phrases in an inﬁnite assortment, and might in truth provide diﬀerent effects in keeping with the way during which it was once performed.
