What's the difference between knowledge and wisdom?
They aren't heterogeneous, and you can know lots of things and have no wisdom at all. Between knowledge and action there is an abyss, but that abyss shouldn't prevent us from trying to know as much as possible before making a decision. Philosophy is the love of wisdom. Philia is love and sophia is wisdom, so the duty to be wise is what philosophy is. Nonetheless, decisions don't depend exclusively on knowledge. I try to know as much as possible before making a decision, but I know that at the moment of the decision I'll make a leap beyond knowledge.
