Aristotle Said

I think that such a mind, an educated mind, is therefore not a mind defined by the volumes of information crammed within the grey matter.

Rather an educated mind is a mind that can take a thought and hold that thought up for inspection and consideration. If there's a mental hand in the brain it certainly would hold the thought for closer scrutiny, and judge its value, moral or otherwise. There is, as it were, an emotional distance between the thought and the mind, lest an irrational and emotional attachment be formed which might jeopardise the brain's integrity.

It is the fool who would accept every thought as worthy and of great value, without exercising discernment and evaluation. And if a person were to accept every thought as the golden truth, that is the road into confusion and dissonance.
Worthy thoughts, noble thoughts, good thoughts are to be stored while those that are not, should be discarded without hesitation after examination.

I choose to take such a path as Paul did - "Finally, brothers, whatever is true, whatever is honourable, whatever is just, whatever is pure, whatever is lovely, whatever is commendable, if there is any excellence, if there is anything worthy of praise, think about these things." Philippians 4:8
