Man is the highest product of his own history. The Discoverer finds nothing so tall as himself, nothing so valuable to him. [ Theodore Parker ]

Columbus died in utter ignorance of the true nature of his discovery. He supposed he had found India, but never knew how strangely God had used him. So God piloted the fleet. The great discoverer, with all his heroic virtues, did not know whither he went. He sailed for the back door of Asia, and landed at the front door of America, and knew it not. He never settled the continent. Thus far and no farther, said the Lord. His providence was over all. [ David James Burrell ]

There are chords in the human heart - strange varying strings - which are only struck by accident; which will remain mute and senseless to appeals the most passionate and earnest, and respond at last to the slightest casual touch. In the most insensible or childish minds there is some train of reflection which art can seldom lead or skill assist, but which will reveal itself, as great truths have done, by chance, and when the discoverer has the plainest and simplest end in view. [ Dickens ]
