[Conflict can be defined] as the opposition of approximately equally strong field forces. - Kurt Zadek Lewin

In psychology one can begin to describe the whole situation by roughly distinguishing the person (P) and his environment (E). Every psychological event depends upon the state of the person and at the same time on the environment, although their relative importance is different in different cases.

The essential meaning of such an assertion is this: events a and b are necessarily dependent moments of a single unified occurrence . The mathematical formula states the quantitative relations involved in the occurrence. Already in such cases the dependent moment of the occurrence are moments that obtain temporally by side.

A conflict is to be characterized psychologically as a situation in which oppositely directed, simultaneously acting forces of approximately equal strength work upon the individual.
