definition.^* But, at any rate, to think the Greek conception
of knowledge was all wrong in that they thought
that one must advance in direct attack upon this
ἐπιστήμη; and attached little value to any knowledge
that did not manifestly tend to that. To look upon
science in that point of view in one's classification is
to do throw modern science into confusion.

{Marginal note: ^* I do not mean to deny, that those theorems are deducible from the definition.
All that is here being urged turns on the falsity of the old notion that all deduction is colollarial deduction.}

Another fault of many classifications, -- or if not
a fault, it is at least a purpose very different from
that which I would undertake to pursue should be bold enough to attempt, -- is that
they are classifications not of science as it exists,
but as of [some?] systematized knowledge such as the
classifier hopes may some time exist. I do not
believe it is possible to have that intimate acquaintance
with the science of the indefinite future that the
discovery of its the real and natural classification of it
