AND EXISTENCE

- The Supreme
Principles of Being
A principle is that
from which something else proceeds in any way
whatever. The supreme principles of
being are those highest principles which are
immediately derived from the concept of
being. These
are important for us to understand as we proceed
with our study of metaphysics. These principles
cannot, strictly speaking, be proved.
Deny them, however, and
all rational discussion must cease. There is no
point in debating the truth of these metaphysical
principles of being. They are, simply and
unequivocally, true.
The principle of
identity tells us that whatever is, is.
Furthermore, it tells us that whatever is not, is
not. Everything is what it is and everything is its
own being. Put simply: being is being and non-being
is non-being.
The principle of
contradiction tells us that it is impossible for a
thing to be and not to be at the same time (within
the same "context"). A being cannot be
and not be some being at the same time. It should
be kept in mind that "at the same time" implies "in
the same respect" or "from the same point of
view."
The principle of
excluded middle tells us that a being either is or
is not. Every being must either be or not
be. There is no middle ground between
being and non-being; no middle being is
possible.
The principle of
sufficient reason tells us that nothing exists
without a sufficient reason. Every being
must have a sufficient reason for its being and
existence.
The most important and
fundamental of these principles is the principle of
contradiction. This stands to reason
since the principles of excluded middle and
sufficient reason are a development of the
principle of contradiction. Furthermore, the
principle of identity is simply another way of
expressing the principle of contradiction.
We can say, therefore,
that the principle of contradiction is the basic
principle of being.
