MENTOGRAPH--A cognitive factor consisting of a complete perception fused or in coalescence with a memory-image. Pure memory, of itself, is without utility as an aid to cognition; but, when nourished or supplemented by the substance of perception it becomes the basis of intellectual consciousness. METAGEOMETRY (Gr. Meta, beyond, transcending--geometry)--Commonly, any kind of geometry that differs from the Euclidean, as the non-Euclidean; a geometry based upon the assumption that the angular sum of a triangle is greater or less than two right angles; the highest form of geometry; a system of idealized mathematical constructions. Sometimes called "pangeometry"; designated by GAUSS as "Astral Geometry"; the geometry of hyperspace. It consists of results arrived at by geometers in seeking a proof of the parallel-postulate. META-SELF--The higher self in man; the universal self; the one self of which all individual selves are but fragments or parts. In man, it is coördinate with the omnipsyche (q.v.) and as such is the medium of kosmic consciousness. MORPHOGENY (Gr. Morphe, form, vehicle, body--geny, evolution)--The evolution of forms, the production of individual bodies or vehicles for life, including organs and faculties. Morphogenic--a derivative; pertaining to morphogeny; a kosmic process (vide figs. 17 and 18). _N_-DIMENSIONALITY--Quality of conceptual space by virtue of which it may be regarded as possessing an indefinite number of dimensions. NEAR-TRUTH--Any statement or view which is based upon partial knowledge; predicates concerning a class or genus derived from limited acquaintance with particulars of the class or genus; statements based upon logical determinations inhering in idealized constructions and applied to concrete or objective conditions; an abstraction viewed as a reality; the application of the qualities of abstractions to realities. NEUROGRAM--Psychologically, a movement received by the afferent nerves in the form of a stimulation and transmitted through the brain and efferent nerves as either a reflex or voluntary action; a nerve impulse; a perception; a primary unit of intellectual consciousness; cf. _Intuitogram_.
