~}{~GREEK SMALL LETTER IOTA WITH PSILI AND PERISPOMENI~}{~GREEK SMALL LETTER DELTA~}{~GREEK SMALL LETTER OMICRON~}{~GREEK SMALL LETTER FINAL SIGMA~} or species in its original sense, one man
might be said to be like another in his {~GREEK SMALL LETTER EPSILON~}{~GREEK SMALL LETTER IOTA WITH PSILI AND PERISPOMENI~}{~GREEK SMALL LETTER DELTA~}{~GREEK SMALL LETTER OMICRON~}{~GREEK SMALL LETTER FINAL SIGMA~} or appearance. An ape, too,
might quite truly be said to have the same {~GREEK SMALL LETTER EPSILON~}{~GREEK SMALL LETTER IOTA WITH PSILI AND PERISPOMENI~}{~GREEK SMALL LETTER DELTA~}{~GREEK SMALL LETTER OMICRON~}{~GREEK SMALL LETTER FINAL SIGMA~} or species or appearance
as a man, without any prejudice as to their common origin. People might
also speak of different {~GREEK SMALL LETTER EPSILON~}{~GREEK SMALL LETTER IOTA WITH PSILI AND OXIA~}{~GREEK SMALL LETTER DELTA~}{~GREEK SMALL LETTER ETA~} or forms or classes of things, such as
different kinds of metals, or tools, or armor, without committing
themselves in the least to any opinion as to their common descent.

Often it would happen that things belonging to the same {~GREEK SMALL LETTER EPSILON~}{~GREEK SMALL LETTER IOTA WITH PSILI AND PERISPOMENI~}{~GREEK SMALL LETTER DELTA~}{~GREEK SMALL LETTER OMICRON~}{~GREEK SMALL LETTER FINAL SIGMA~}, such as the
white man and the negro, differed in their {~GREEK SMALL LETTER EPSILON~}{~GREEK SMALL LETTER IOTA WITH PSILI AND PERISPOMENI~}{~GREEK SMALL LETTER DELTA~}{~GREEK SMALL LETTER OMICRON~}{~GREEK SMALL LETTER FINAL SIGMA~} or appearance; often also
that things belonged to the same {~GREEK SMALL LETTER EPSILON~}{~GREEK SMALL LETTER IOTA WITH PSILI AND PERISPOMENI~}{~GREEK SMALL LETTER DELTA~}{~GREEK SMALL LETTER OMICRON~}{~GREEK SMALL LETTER FINAL SIGMA~}, such as eatables, differed in
their {~GREEK SMALL LETTER GAMMA~}{~GREEK SMALL LETTER EPSILON WITH OXIA~}{~GREEK SMALL LETTER NU~}{~GREEK SMALL LETTER OMICRON~}{~GREEK SMALL LETTER FINAL SIGMA~}, as, for instance, meat and vegetables.

All this is clear and simple. The confusion began when these two terms,
instead of being cooerdinate, were subordinated to each other by the
philosophers of Greece, so that what from one point of view was called a
_genus_, might from another be called a species, and _vice versa_. Human
beings, for instance, were now called a _species_, all living beings a
_genus_, which may be true in logic, but is utterly false in what is older
than logic--viz., language,
