Volcanic action is essentially paroxysmal; yet Mr. Lyell will admit no greater paroxysms than we ourselves have witnessed-no periods of feverish spasmodic energy, during which the very framework of nature has been convulsed and torn asunder. The utmost movements that he allows are a slight quivering of her muscular integuments.
Adam Sedgwick[Vestiges begins] from principles which are at variance with all sober inductive truth. The sober facts of geology shuffled, so as to play a rogue's game; phrenology (that sinkhole of human folly and prating coxcombry); spontaneous generation; transmutation of species; and I know not what; all to be swallowed, without tasting and trying, like so much horse-physic!! Gross credulity and rank infidelity joined in unlawful marriage, and breeding a deformed progeny of unnatural conclusions!
Adam SedgwickAs a system of philosophy it is not like the Tower of Babel, so daring its high aim as to seek a shelter against God's anger; but it is like a pyramid poised on its apex.
Adam SedgwickWe cannot take one step in geology without drawing upon the fathomless stores of by-gone time.
Adam SedgwickThe world is not as it was when it came from its Maker's hands. It has been modified by many great revolutions, brought about by an inner mechanism of which we very imperfectly comprehend the movements; but of which we gain a glimpse by studying their effects: and their many causes still acting on the surface of our globe with undiminished power, which are changing, and will continue to change it, as long as it shall last.
Adam SedgwickConsidered as a mere question of physics, (and keeping all moral considerations entirely out of sight,) the appearance of man is a geological phenomenon of vast importance, indirectly modifying the whole surface of the earth, breaking in upon any supposition of zoological continuity, and utterly unaccounted for by what we have any right to call the laws of nature.
