In any case, we can already say in advance, on the basis of insight, that the psychic, considered purely in terms of its own essence, has no physical nature, has no conceivable in itself in the natural sense, no spatiotemporally causal, no idealizable and mathematizable in itself, no laws after the fashion of natural laws; here there are no theories with the same relatedness back to the intuitive life world, no observations or experiments with a function for theorizing similar to natural science in spite of all the self misunderstandings of empirical, experimental psychology.
