Truth
Man’s mind, once stretched by a new idea, never regains its original dimension. (Oliver Wendell Holmes, famous 19th-century American physician and poet)
That truth just might be a two-edged sword. If an evil idea is introduced into our thinking, we might not be able to disregard it, and it could lead to evil behavior. We’d prefer to look at it more positively. When good ideas are introduced, they provide an impetus to move forward, to expand our thinking, and to pursue worthy goals.
So I turned my mind to understand, to investigate and to search out wisdom and the scheme of things (Ecclesiastes 7:25).
