that this thought "I" is an act, we have now said enough to establish this important truth in psychology, that man, when philosophising concerning himself, does not do well to commence with the contemplation, or with any consideration of himself as a Being (we say this with an especial eye to the substance and doctrine of "Mind"), for his proper Being is but a secondary articulation in his actual development, and therefore ought to form but a secondary step in his scientific study of himself, and ought to hold but a subordinate place in his regard. But he ought to commence with the contemplation of himself as an act (the act of consciousness), for this is, in reality, his true and radical beginning; and, therefore, in speculation he ought to follow the same order; and, copying the living truth of things in his methodical exposition of himself, should take this act as the primary commencement or starting-point of his philosophical researches. Such, in our opinion, is the only true method of psychological science.
