ABSTRACT
Subjective difficulties in regard to theory can be divided into two main groups, viz. an anxiety group and an obsessional group. The reactions in question need not necessarily indicate the presence of an anxiety hysteria or an obsessional neurosis; in many cases they are simply characterological reactions. The main features of the anxiety group are that analytical theory functions as a substitutive anxiety idea, and a degree of fear of theory is exhibited together with over-estimation of it. The idea that analytical theory is too complicated also justifies reassurance. The structure of analytical theory is certainly not more complicated than the structure of physiological theories concerning the function of the liver. But there is one other difficulty in approaching analytical theory which cannot be dealt with by reassurance. It is inherent in the nature of the mental apparatus and is therefore a permanent obstacle. It is the difficulty of thinking psychologically.
