If the basis of the constructional system is autopsychological, then the  danger of subjectivism seems to arise. Thus, we are confronted with the  problem of how we can achieve objectivity of knowledge 61 with such a  system form. The requirement that knowledge be objective can be under- stood in two senses. It could mean objectivity in contrast to arbitrariness:  if a judgment is said to reflect knowledge, then this means that it does  not depend on my whims. Objectivity in this sense can obviously be  required and achieved even if the basis for knowledge is autopsychological.
