If we wish, then, to remain within the narrow but safe limits
within which science can attain to knowledge, and not to wander
in the domain of vague conjecture and vain hypothesis, all we
must do is simply to take note of such phenomena as are
accessible to us, and confine ourselves to their consideration.
Every conclusion drawn from our observation is, as a rule,
premature, for behind the phenomena which we see clearly are
other phenomena that we see indistinctly, and perhaps behind
these latter, yet others which we do not see at all.
