Bertrand Russell, "Principles of Mathematics" 2010 | pages: 601| ISBN: 020386476X | DJVU | 4 mb The present work has two main objects. One of these, the proof that all pure mathematics deals exclusively with concepts de∩¼ünable in terms of a very small number of fundamental logical concepts, and that all its propositions are deducible from a very small number of fundamental logical principles, is undertaken in Parts II.ΓÇöVII. of this Volume, and will be established by strict symbolic reasoning in Volume II. The demonstration of this thesis has, if I am not mistaken, all the certainty and precision of which mathematical demonstrations are capable. As the thesis is very recent among mathematicians, and is almost universally denied by philosophers, I have undertaken, in this volume, to defend its various parts, as occasion arose, against such adverse theories as appeared most widely held or most di∩¼âcult to disprove. I have also endeavoured to present, in language as untechnical as possible, the more important stages in the deductions by which the thesis is established.
