Your inability to see the wisdom in someone else is not a reflection on their lack of perspicacity, it is a reflection on yours. - Ilyas Kassam
I intend to bring you strength, joy, courage, perspicacity, defiance. - André Gide
Heat and animosity, contest and conflict, may sharpen the wits, although they rarely do; they never strengthen the understanding, clear the perspicacity, guide the judgment, or improve the heart.
