Natural - Theoretical
Many discussions can separate people into
two groups.
1) Those that claim that something is natural, arising with humankind's
development.
2) Those that argue that something is theoretically possible; therefore
it has the right to be considered.
Let's take a straightforward example -
vegetarianism. More provocative examples are sexual orientation and discrimination
of many stripes.
The Natural Group - these people take their premises
from nature. We've always been this way. We evolved this way. Nature intended
(the teleological nuance is probably appropriate here) for people to eat
animals. Therefore it's okay.
The Theoretical Group - these people say that we don't need
to eat animals. It's theoretically possible to live without eating animals.
Therefore, the eating of animals is a gratuitous act that could be avoided.
Both groups are being logical - what is different is the
premises they start from.
