argument & validity

"The present day shows with appalling clarity how little able people are to let the other man's argument count, although this capacity is a fundamental and indispensable condition for any human community. Everyone who proposes to come to terms with himself must reckon with this basic problem. For, to the degree that he does not admit the validity of the other person, he denies the "other" within himself the right to exist - and vice versa..." - Carl Jung
