time points of dissimilarity, such as to make the two principles appear
radically unlike.

This brief summary presents nearly all that we can satisfactorily make
out respecting instinct; and at the same time it shows how much is
still wanting to a complete solution of all the questions which it
involves. And then there are higher mysteries connected with the
subject, which we do not attempt to penetrate,--mysteries in regard to
the creation and the maintenance of instinctive action: whether it be
the result of particular external conditions acting on the organization
of animals, or whether, as Sir Isaac Newton thought, the Deity himself
is virtually the active and present moving principle in them;--and
mysteries, too, about the future of the brute world: whether, as
Southey wrote,

"There is another world
For all that live and move,--a better world."

If we ever find a path which seems about to lead us up to these
mysteries, it speedily closes against us, and leaves us without any
rational hope of attaining their solution.
