Hutton, James, 1726-1797

"Theory of the Earth, Volume 1 (of 4)"


To my argument, That these porous strata are found _consolidated with
every different species of mineral substance_, our author makes the
following observation: "Here the difficulties to the supposition of an
aqueous solution are placed in the strongest light; yet it must be owned
that they partly arise from the author's own gratuitous supposition,
that strata existed at the bottom of the sea previous to their
consolidation;"--gratuitous supposition!--so far from being a
supposition of any kind, it is a self evident proposition; the terms
necessarily imply the conclusion. I beg the readers attention for a
moment to this part of our author's animadversion, before proceeding to
consider the whole; for, this is a point so essential in my theory,
that if it be a gratuitous supposition, as is here asserted, it would
certainly be in vain to attempt to build upon it the system of a world.
That strata may exist, whether at the bottom of the sea, or any other
where, without being consolidated, will hardly be disputed; for, they
are actually found consolidated in every different degree.
