  By ‘unity of consciousness’, Kant seems to have the following in mind: I am conscious not only of single experiences but of a great many experiences at the same time. The same is true of actions; I can do and be conscious of doing a number of actions at the same time. In addition to such synchronic unity, many global representations, as we called them, display temporal unity: current representation is combined with retained earlier representation. (Temporal unity is often a feature of synthesis of recognition.) Any representation that we acquire in a series of temporal steps, such as hearing a sentence, will have unity across time (A104; A352).
