which do not more or less depend upon the science of
logic. One of these five is Logic itself, which must
contrive, by hook or by crook, to work out its own
salvation without a full preacquaintance with its own
discoveries, but which, like any other science, will
lay one stone upon another in the erection of its doctrine.
This is the last of the five. The first is Mathematics, which
mathematics may itself be regarded as an art of reasoning_[?]
Perhaps this is not the highest conception of it_[?] But at
any rate, mathematics has no occasion to inquire into the theory of the
validity of its own argumentations; for these are more
evident than any such theory could be. The second of
the five is that department of philosophy called Phenomono-
logy, whose business it is simply to draw up an inven-
tory of appearances without going into any investiga-
tion of their truth. The third is Esthetics, if I am
to take the word of others that there is such a science,
I myself being lamentably ignorant of it, as I fear will too plainly appear.
