* The title refers to Nathaniel Branden’s lecture “The Concept of God,” from his lecture series “The Basic Principles of Objectivism.” That lecture is fully transcribed in his book The Vision of Ayn Rand, chapter 4. Partial and perhaps complete audios seem to be available throughout the Internet. See also R.A. Childs, “The Epistemological Basis of Anarchism,” Note 19.

MM... the meaning of a concept consists of its units.

MM... to define “existence,” one would have to sweep one’s arm around and say: “I mean this.”

A. Rand, “Introduction to Objectivist Epistemology,” 5/12/3b [December 1966] and IOE 53 [Expanded Edition: 56].
MMExistence and identity are not attributes of existents, they are the existents.... The units of the concepts of “existence” and “identity” are every entity, attribute, action, event, or phenomenon (including consciousness) that exists, has ever existed or ever will exist.

MMAnd since a concept is an integration of units, it has no content or meaning apart from its units. The meaning of a concept consists of the units — the existents — which it integrates, including all the characteristics of these units.

MMObserve that measurement consists of relating an easily perceivable unit to larger or smaller quantities, then to infinitely larger or infinitely smaller quantities which are not directly perceivable to man. (The word “infinitely” is used here as a mathematical, not a metaphysical, term.)

A. Rand, “Introduction to Objectivist Epistemology,” 5/7/11b and IOE 21 [Expanded Edition: 18].
MMAn arithmetical sequence extends into infinity, without implying that infinity actually exists; such extension means only that whatever number of units does exist, it is to be included in the same sequence.

MMTime is “in” the universe; the universe is not “in” time.
