When young, I was puzzled that metaphysical and philosophic writing tended, almost always, to come across as intellectual masturbation. I eventually realised that reality is hard to handle, particularly for those inclined to fantasy. Esotericism becomes a handy refuge, an ecosystem not merely inhabited by astrologers for that reason. The wise, limited to a focus on the real, impress less. Saturn confronts us with reality, but our imagination transcends reality.
Reality binds the mind.
The normal practice of science requires the experimental testing of hypotheses in order to reveal a 'truth'. By which I mean an apparent fact of nature, a feature of reality. Replication either confirms or discredits the revealed 'truth'. Acceptance by scientists that something is real or true is relative however, just as for anyone else. Typically, as time passes a consensus beds in, one way or the other.
