(For example, number of sides is # a common characteristic which can be used to differentiate between # triangles and rectangles.) # consciousness is the faculty of perceiving that which exists. # definition is a statment that identifies the nature of the units # subsumed under a concept. (The purpose of a definition is to # distinguish a concept from all other cocnepts and thus to keep its # units differentiated from all other existents.) # differentia is the distinguishing characteristic(s) which separate # the units of the concept being defined from all other existents # subsumed under the genus of the concept. # epistemology is the science of the discovery of the proper methods # of acquiring and validating knowledge. # essential characteristic is the distinguishing characteristic that # explains the greatest number of other characteristics. (Metaphysically, # the distinctive characteristic which makes possible the greatest # number of other characteristics.) # genus of a concept is the wider class of existents which share a conceptual # common denominator(s) with the existents subsumed by the concept # being defined. # grammar is the science which deals with the formulation of the # proper methods of verbal expression and communication (i.e., the # methods of organizing words into sentences). # knowledge is a mental grasp of a fact(s) of reality, reached either # by perceptual observation or by a process of reason based on # perceptual observation. # language is a code of visual-auditory symbols that serves the # psycho-episemological function of converting concepts into the # mental equivalent of concretes. # logic is the art of noncontradictory identification. # measurement is the identification of a quantitative relationship # established by means of a standard that serves as a unit. (The # purpose of measurement is to expand the range of man's consciousness, # beyond the perceptual level.) # meaning of a concept is the existents subsumed under the concept. # number is a mental symbol that integrates units into a single larger # unit (or subdivides a unit into fractions) with reference to the basic # number of "one", which is the basic mental symbol of "unit". # percept is a group of sensations automatically retained and integrated # by the brain of a living organism. # science is an organized body of knowledge, acquired by and communicable # to a human consciousness. # similarity is the relationship between two or more existents which # possess the same characteristic(s), but in different measure or degree. # unit is an existent regarded as a separate member of a group of two # or more similar members. # word is a visual-auditory symbol used to represent a concept.
