_The Eighth Trope_. The Trope based upon relation contains, as
Sextus rightly remarks, the substance of the other nine,[1] for
the general statement of the relativity of knowledge includes
the other statements made. The prominence which Sextus gave this
Trope in his introduction to the ten Tropes leads one to expect
here new illustrations and added[2] arguments for [Greek:
epoche]. We find, however, neither of these, but simply a
statement that all things are in relation in one of two ways,
either directly, or as being a part of a difference. These two
kinds of relation are given by Protagoras, and might have been
used to good purpose in the introduction to the Tropes, or at
the end, to prove that all the others were really subordinate to
the eighth. The reasoning is, however simply applied to the
relation of objects to each other, and nothing is added that is
not found elsewhere where as an argument for [Greek: epoche].[3]
This Trope is the tenth by Diogenes, and he strengthens his
reasoning in regard to it, by a statement that Sextus does not
directly make, _i.e._, that everything is in relation to the
understanding.[4]

_The Ninth Trope_. This is based upon the frequency and rarity
of events, and refers to some of the phenomena of nature, such
as the rising of the sun, and the sea, as no longer a source of
astonishment, while a comet or an earthquake are wonders to
those not accustomed to them.[1] The value of objects also
depends on their rarity, as for example the value of gold.[2]
Furthermore, things may be valuable at one time, and at another
not so, according to the frequency and rarity of the
occurrence.[3] Therefore this Trope also leads to [Greek:
epoche]. Diogenes gives only two illustrations to this Trope,
that of the sun and the earthquake.[4]

_The Tenth Trope_. We have already remarked on the difference in
the character of the tenth Trope, dealing as it does, not with
the ideas of objects, like the other nine Tropes, but with
philosophical and religious opinions, and questions of right and
wrong. It was the well-known aim of the Sceptics to submit to
the laws and customs of the land where they
