Small people delight in what they call consistency-that is, it gives them immense pleasure to say that they believe now exactly as they did ten years ago. This simply amounts to a certificate that they have not grown-that they have not developed-and that they know just as little now as they ever did. The highest possible conception of consistency is to be true to the knowledge of today, without the slightest reference to what your opinion was years ago.

It is the rainbow -- Hope shining upon the tears of grief.

If the account given in Genesis is really true, ought we not, after all, to thank this serpent?
