ABSTRACT
Η The applicability of the energie standpoint to psychology rests, then, exclusively on the question whether a quantitative estimate of psychic energy is possible or not. This question can be met with an unconditional affirmative, since our psyche actually possesses an extraordinarily well-developed evaluating system, namely the system of psychological values. Values are quantitative estimates of energy. Here it should be remarked that in our collective moral and aesthetic values we have at our disposal not merely an objective system of value but an objective system of measurement. This system of measurement is not, however, directly available for our purpose, since it is a general scale of values which takes account only indirectly of subjective, that is to say individual, psychological conditions.
