True understanding of a man and estimate of his character can only be arrived at by methods at once more comprehensive and more subtle than those commonly employed among men. Everything that he sees, does, and suffers has its influence on the moulding of his character; and he must be considered in relation to his physical environment, no less than to his race and ancestry. Christopher Columbus spent a great part of his active life on the sea; it was sea-life which inspired him with his great Idea, it was by the conquest of the sea that he realised it; it was on the sea that all his real triumphs over circumstance and his own weaker self were won. The influences at work upon a man whose life is spent on the sea are as different from those at work upon one who lives on the fields as the environment of a gannet is different from the environment of a skylark: and yet how often do we really attempt to make due allowance for this great factor and try to estimate the extent of its moulding influence?
To live within sound or sight of the sea is to be conscious of a voice or countenance that holds you in unyielding bonds. The voice, being continuous, creeps into the very pulses and becomes part of the pervading sound or silence of a man’s environment; and the face, although it never regards him, holds him with its changes and occupies his mind with its everlasting riddle. Its profound inattention to man is part of its power over his imagination; for although it is so absorbed and busy, and has regard for sun and stars and a melancholy frowning concentration upon the foot of cliffs, it is never face to face with man: he can never come within the focus of its great glancing vision. It is somewhere beyond time and space that the mighty perspective of those focal rays comes to its point; and they are so wide and eternal in their sweep that we should find their end, could we but trace them, in a condition far different from that in which our finite views and ethics have place. In the man who lives much on the sea we always find, if he be articulate, something of the dreamer and the mystic; that very condition of mind, indeed, which we have traced in Columbus, which sometimes led him to such heights, and sometimes brought him to such variance with the human code.
