““In the foundations of law, or mathematics, or science, or art, or child rearing,… [the] issues constitute a polarity extending from the extreme left through a middle of the road position to the extreme right-wing position. The issues are simple enough. Is man the measure, an end in himself, an active, creative, thinking, desiring, loving force in nature? Or must man realize himself, attain his full stature only through struggle toward, participation in, conformity to a norm, a measure, an ideal essence basically prior to and independent of man?””
