“The man who sees both sides of a question is a man who sees nothing at all.”
So says, Oscar Wilde. Not sure I agree. The person who sees both sides is precisely the person who sees. But if it simply means seeing both sides with nothing flowing from it, then the person does see nothing at all.
The ability to see both sides of an issue needs to inform and lead to decision and action. Only holistic seeing and thinking nurtures wise opinion, decision and action.
