Affect. Emotional reactions marked by physical symptoms and disturbances in thinking. (See also complex and feeling.)
Affect is invariably a sign that a complex has been activated.
Affects occur usually where adaptation is weakest, and at the same time they reveal the reason for its weakness, namely a certain degree of inferiority and the existence of a lower level of personality. On this lower level with its uncontrolled or scarcely controlled emotions one . . . [is] singularly incapable of moral judgment. [The Shadow, Aion, CW9ii, par. 15.]
