mind; therefore, we must observe and determine its various forms of activity. These activities, classified under a few general categories original: "heads" and attributed to original: "predicated of" the unseen something which expresses them, will give us a definition of mind."
The act of consciousness confirms the existence of Mind in the person experiencing it. No one can be conscious of a thought and, at the same time, deny that they have a mind. This is because the very act of denial is, in itself, an expression original: "manifestation" of thought and consequently an assertion that the mind exists. One may state the axiom axiom A self-evident truth that requires no proof.: "I think, therefore, I have a mind" This is a variation of the famous statement by René Descartes: Cogito, ergo sum (I think, therefore I am).; but one cannot logically argue: "I think, therefore, I have no mind." The mind has a definitive and final knowledge of its own existence.
The older view of the Mind is that it is something superior to physical matter, which it uses to express itself. It was believed to be unknowable in its own essence and could only be studied through its outward actions. It was supposed to intertwine original: "involve" itself with matter in some way, and to express itself there in an infinite variety of forms, levels, and variations.
