Reason is a sense

The problem with early philosophy is that, while they anticipated the
falsabilty of the senses, they elevated reason as an unerring way to
devise truth. This is evident in the ethics of the sophists as well as
the Socratan schools of thought.

But it should be evident that reason is often as equally fallable as
false perception through the senses, not for the least of reasons but
that reasoned conclusions are often tainted by physical perceptions.

Therefore it is more properly conceived as a sense itself. This sixth
of the senses is an equal part of the perceptional system. Peceived
taste is affected by smell. Sight can be altered by an accompanying
sound. And so too, reason is impacted by all it's five cousins.

Once this conclusion is reached, we are better capable of reigning in
the conjectures of reason and placing it squarely within the bounds of
the healthy skepticism to which an honest person applies to all
perceptional instruments.
