Wilhelm von Humboldt Quote

Death is but a word to us. One's own experience alone can teach us the real meaning of the word. The sight of the dying does little. What one sees of them is merely what precedes death: dull unconsciousness is all we see. Whether this be so,--how and when the spirit wakes to life again,--this is what all wish to know, and what never can be known until it is experienced.
