It was simply a case of differing definitions of quid pro quo.
But admitting the validity of this criticism, and even going so far as to question the possibility of ever devising absolutely inclusive and, at the same time, exclusive definitions, no sufficient reason is adduced for giving up all attempt at morphological analysis.
With these definitions it is now possible to prove the following six premisses applying to finite cardinal numbers, from which Peano 2 has shown that all arithmetic can be deduced i.
The definitions of the finite ordinals can be expressed without use of the corresponding cardinals, so there is no essential priority of cardinals to ordinals.
Contrasting the above definitions of number, cardinal and ordinals, with the alternative theory that number is an ultimate idea incapable of definition, we notice that our procedure exacts a greater attention, combined with a smaller credulity; for every idea, assumed as ultimate, demands a separate act of faith.
The arithmetic of rational numbers is now established by means of appropriate definitions, which indicate the entities meant by the operations of addition and multiplication.
These entities are not created by mathematicians, they are employed by them, and their definitions should point out the construction of the new entities in terms of those already on hand.
The arithmetic of real numbers follows from appropriate definitions of the operations of addition and multiplication.
But an indefinite number of definitions of the product of two complex numbers yield interesting results.
We frequently meet with cogredient and contragedient quantities, and we have in general the following definitions:-(i) " If two equally numerous sets of quantities x, y, z,...
The second includes definitions of technical terms in common use, together with so much of the elementary theory as is necessary for understanding the experimental work described in subsequent portions of the article; a number of formulae and results are given for purposes of reference, but the mathematical reasoning by which they are obtained is not generally detailed, authorities being cited whenever the demonstrations are not likely to be found in ordinary textbooks.
He is not prepared to exclude the great medieval pronouncements, or the modern Roman Catholic definitions, from the list of dogmas; but on the whole he prefers to keep in view " one historical species " - Loofs suggests that he ought perhaps rather to say one individual type - that greatest group of Christian dogmas which " was created by the Greek spirit upon the soil of the gospel " (Hist.
A discussion of these concepts and the various definitions of angles in Euclidean geometry is to be found in W.
Let's address that by looking at two phenomena: the changing definitions of poverty over time, and the effect of a large gap between the incomes of the rich and poor.
I am going to use definitions of my own in order to draw a contrast between two ideas that I consider very different—one peaceful and one not.
What many children think of with dread, as a painful plodding through grammar, hard sums and harder definitions, is to-day one of my most precious memories.
In investigating any subject there must occur at the beginning words and phrases which cannot be adequately understood until the pupil has made considerable advancement; yet I have thought it best to go on giving my pupil simple definitions, thinking that, although these may be somewhat vague and provisional, they will come to one another's assistance, and that what is obscure to-day will be plain to-morrow.
