“Integrity without knowledge is weak and useless, and knowledge without integrity is dangerous and dreadful.”

Certainly, knowledge without integrity is dangerous and, potentially, dreadful; but can one have integrity without knowledge ? The word's root is "integral", or tied together, somehow. We must be careful that our assumptions, or experiences, have brought us to correct conclusions upon which our sense (?) of integrity can be based. This, of course, leads to a discussion of ethics and morals which may or may not be essential to the topic of integrity. I do not believe the statement is symmetrical.

A Gifted Man in Time no Doubt,
His faith of loyal in time of drought.

One might ask what is the surrounding context to the quote, but on the surface no truer a statement could be made concerning politicians and generals.
Tools of Knowledge and Skills of Understanding, must be joined hand in hand to be of any value. Experience is a guide best suited for a child of Integrity.
