mathesis definition

“Psychotherapy” is a masterpiece, but his psychic equation of _causative_ and _purposive_, with all his mathesis, not only remains unsolved, but leads to confusion, from the false light shed on the unknown quantity, and his failure to indicate the gnosis; the demarcation between automatism and purposive Intelligence.
But Paul Yoder, also drawing on contemporary sciences which have posed a challenge to the classical mathesis, makes a very different argument.
