This expansive instinct-process becomes with the accretion of memory-images the impulse of generosity which adapts the individual to the conditions of a larger world. This impulse forms impulse-centers. Compassion differs from generosity in that it is an impulsive reaction to a feeling-state which is agitative as well as expansive. Compassion may occur in instinctive form in the parental relation as a reaction to the babe as puny and helpless.*®

The new-born babe smiles when "comfortable"'^'^ and cries when in pain. Cooley writes.
