When swimming under water, it is a very sobering thing suddenly to look a large octopus in the face. One never forgets it: one’s respect, yet one’s feeling of the hopelessness of any real intellectual sympathy. One is soon reduced to mere physical admiration, like any silly painter, of the cow-like tenderness of the eye, of the beautiful and infinitesimal mobility of that large and toothless mouth, which accepts as a matter of course that very water against which you, for your life’s sake, must be holding your breath. There he reposes in a fold of rock, apparently weightless in the clear green medium but very large, his long arms, suppler than silk, coiled in repose, or stirring in recognition of your presence. Far above, everything is bounded by the surface of the air, like a bright window of glass. Contact with a small baby can conjure at least an echo of that feeling in those who are not obscured by an uprush of maternity to the brain.

Of course it is not really so cut-and-dried as all this; but often the only way of attempting to express the truth is to build it up, like a card-house, of a pack of lies.
