This section covers some of the more basic notions associated with the complex-valued random signals field and introduces a new class of signals, called widely factorizable.
When analysis shows the terminology and presuppositions of one stage of analysis to be definable, or logically constructible, in terms of simpler and more basic notions, this is a philosophical advance, even if these notions are themselves further analyzable.

Thus, rather than treating admirable character traits as more basic than the notions of right and wrong conduct, Kant takes virtues to be explicable only in terms of a prior account of moral or dutiful behavior.
