“We need the tonic of wildness...At the same time that we are earnest to explore and learn all things, we require that all things be mysterious and unexplorable, that land and sea be indefinitely wild, unsurveyed and unfathomed by us because unfathomable. We can never have enough of nature.”

“Criticism is an act of love. We can never learn those people we love, but we can learn about them in such ways as to perceive more clearly that unfathomable, mysterious core that is the source of their beauty.”

“Woman is the unfathomable, incalculable mystery, the problem that we men can never hope to solve.”

“Our apparitions, the things you know us by, are simply childish. Beneath it is all dark, it is all spreading, it is unfathomably deep; but now and again we rise to the surface and that is what you see us by.”

“We see only a part of the surface of things. The rest will be forever hidden from us, to be appreciated for its felt but unfathomed presence.”

“We are not grand because we are at the top of the food chain or because we can alter our environment - the environment will outlast us with its unfathomable forces and unyielding powers. But rather than be bound and defeated by our insignificance, we are bold because we exercise our will anyway, despite the ephemeral and delicate presence we have in this desert, on this planet, in this universe.”
