Well, such thoughts still don't stop me from being sentimental because I have layers upon layers of mental gymnastics to justify an idea, discredit it, then validate it again through another means. Truly, the human mind is the most entertaining toy one could possess.
Which recently lead me to the thought that another reason why intelligence is not a virtue besides ethics/morals is that intellect is concerned purely with the computation of relationships between relationships of relationships of relatively simple things, resulting in conclusions that are not useful at all.
Kind of how for hundreds and hundreds of years, big brain IQ160 theologians spent considerable mental effort on resolving contradictions and elaborating ambiguities in the christian religion that honestly are not of any importance, value or utility at all, and amount to nothing but mental masturbation. "Bro, did Christ really die on the cross, or did he ascend before death, leaving behind an illusion? Or was it not an illusion, but a body deprived of holy spirit? Bro, what if he died but what died on the cross was not Christ himself, but his purely material aspect? Bro, what about that immaculate conception bro, how does it work?". A bunch of bullshit honestly.
It can be the case that considerable mental processing power is spent for the sake of nothing valuable at all, if intellect has no wisdom to guide it.
