Absence of Liquid Water
Apparent lack of liquid water on Titan's surface has been cited by NASA astrobiologist Andrew Pohorille as an argument against life there. Pohorille considers that water is important not only as the solvent used by "the only life we know" but also because its chemical properties are "uniquely suited to promote self-organization of organic matter". He has questioned whether prospects for finding life on Titan's surface are sufficient to justify the expense of a mission which would look for it.

—Ralph Waldo Emerson (1803–1882)
“We want in every man a long logic; we cannot pardon the absence of it, but it must not be spoken. Logic is the procession or proportionate unfolding of the intuition; but its virtue is as silent method; the moment it would appear as propositions and have a separate value, it is worthless.”
—Ralph Waldo Emerson (1803–1882)
“While the State becomes inflated and hypertrophied in order to obtain a firm enough grip upon individuals, but without succeeding, the latter, without mutual relationships, tumble over one another like so many liquid molecules, encountering no central energy to retain, fix and organize them.”

“The water for which we may have to look
In summertime with a witching wand,
In every wheelrut’s now a brook,
In every print of a hoof a pond.”
—Robert Frost (1874–1963)
