*The decimal numbers assigned to the individual propositions indicate the logical importance of the propositions, the stress laid on them in my exposition. The propositions n.1, n.2, n.3, et cetera. are comments on proposition no. n; the propositions n.m1, n.m2, et cetera. are comments on proposition no. n.m; and so on and so forth; yarda yarda yarda; blah blah blah.
