Lecture VI
Today one finds that even those with eminent minds have forgotten how to engender the necessary subtlety. In the last lecture I made it clear that I have the highest regard for Franz Brentano, not least because he did, through his study of Aristotle, develop subtlety of thinking up to a point. As I said he could not accept spiritual science. This was due to many things, but principally it was because he still lacked the necessary mobility of thinking to penetrate to the spiritual aspect of things. One must at least strive to attain it. When people read my Theosophy or the second part of Occult Science, one can often discover from what emerges just why their thinking stumbles.[^12][^13] The same can be said in regard to Brentano. I would indeed have found it incomprehensible that a sensitive and astute thinker like Brentano should be unable to find the way, had I not succeeded in discovering an exact instance that reveals just where the difficulty lies. There are others, of course, but let me give you an example.
