People & Opinions
I’ve been accused of being fickle with my opinions and even (gasp) holding more than one conflicting position on a subject at one time.
I explained to my adversary that the most efficient way to improve one’s understanding of a subject is to have other people push back against your half-arsed assertions.
The more the merrier; people and opinions.
It seems to work, doesn’t it?

Amen, brother! If no-one ever pushed back against my half-arsed assertions, I shudder to think how rubbish my opinions would be.
