Who said this?!?

Question

I am looked for a quote that is something along the lines of:

A wise (educated?) man looks at both (differing, opposite?) sides of an issue.

I'm sorry I can't give you much more than this, I had written it down almost a year ago and I need to know the quote and who said it!

THANKS!
