An introduction to Individual Philosophy, by means of the spoken or written word, is an interpretation, a particular human being responding to the particular experience of that being.

A speaker or writer makes a particular interpretation born of his subjective experience, translating that experience into words as best he can.

The listener or reader makes a personal interpretation of the original interpretation, according to his particular experience.

At the level of sensory perceived objects, those particular interpretations, for the purpose of communication in the *sensorily perceived world, apparently coincide.

Hence, when the word "apple" is used, two people speaking the same acquired language visualize a similar object. At this level with variable efficiency, the human being, conceiving "apple" as a sensorily perceived object, functions in relation to all other objects in the sensorily perceived reality. But, at a level other than that of the sensorily perceived world, there can be no certainty that interpretations do coincide.

For example, when the word "Consciousness" is used it is not possible for one person to convey to another exactly what he (inwardly) experiences as consciousness. Each must realize for himself what such a word means in his own experience. One can give another apples; one cannot give another consciousness.

One person cannot tell another what consciousness is because of the limitations of spoken and written word. The impossibility arises from the fact that, in order to describe an abstract experience, abstract words have to be used (abstract here meaning that which is other than sensorily perceived or described in terms of sensorily perceived world). And how could it be possible to define the abstract words needed in order to define the abstract?

*sensorily: That which is tangible by the individuals senses. Such as touch, smell, sight, etc.

what is apple?
