For we need only draw all the waves so that they run into each other below the threshold, whilst above it they appear distinct, as in the figure below.
"In this figure a, b, c stand for three organisms, or rather for the total waves of psycho-physical activity of three organisms, whilst A B represents the threshold. In each wave the part that rises above the threshold is an integrated thing, and is connected with a single consciousness. Whatever lies below the threshold, being unconscious, separates the conscious crests, although it is still the means of physical connection.
"In general terms: wherever a psycho-physical total wave is continuous with itself above the threshold, there we find the unity or identity of a consciousness, inasmuch as the connection of the psychical phenomena which correspond to the parts of the wave also appears in consciousness. Whenever, on the contrary, total waves are disconnected, or connected only underneath the threshold, the corresponding consciousness is broken, and no connection between its several parts appears. More briefly: consciousness is continuous or discontinu-
