Frances to listers with another quickie...
The eventual converted use of all signs is preferred as symbols
in logics. Signs are compelled by the effort of signers in the
direction of this good end goal. To test their logical chances,
signs can be first applied in semiotics as to their likely
success in logics. For example, not all signs in arguments need
be verbal for the argument to be sound and good, nor need this
mix be a cause of its logical failure. If one of three proposed
premises in a written syllogism is a pictorial depiction, such as
a graphic pictogram, which should immediately evoke a visual
vision in the mind of its viewer and reader, then it may be
possible for the signer of statements to perform a competent
illocutionary act using other than verbal language signs
exclusively. The signer of the nonverbal and nonlingual depiction
furthermore need not be foreign to the verbal language used. Of
course, linguistic language systems and semiotic signage systems
like graphic pictures are not absolutely necessary for logics,
because logics is assigned its own symbolic system, but even
sound verbal language combined with some sound visual signage is
a good way to prepare signs for logics. The symbols of logics
will nonetheless be degenerative and yield a degraded version of
pure logics, because all that the human mind can do is infer
logics with moderated signs.
