Agnostic... coined by Spencer?

[Mark]

Wasn't it Thomas Huxley who first coined the term (in 1869, if various
atheist net resources are to be believed)?

"Agnosticism is not a creed but a method, the essence of which lies in
vigorous application of a single principle. Positively the principle may be
expressed as: in matters of intellect, follow your reason as far as it can
carry you without other considerations. And negatively, in matters of the
intellect, do not pretend the conclusions are certain that are not
demonstrated or demonstrable. It is wrong for a man to say he is certain of
the objective truth of a proposition unless he can produce evidence which
logically justifies that certainty. That is what Agnosticism asserts; and,
in my opinion, it is all that is essential to Agnosticism. ... The
application of the principle results in the denial of, or the suspension of
judgment concerning, a number of propositions respecting which our
contemporary ecclesiastical "gnostics" profess entire certainty."
