Mortimer Adler calls himself a "Philosopher At Large" (the title of his
1975 autobiography). He acknowledges Aristotle and Thomas
Aquinas as his primary influences.

The six great ideas are:
- Truth
- Beauty
- Goodness
- Liberty
- Equality
- Justice

Adler upholds the correspondence theory of truth : a proposition
is objectively true if it corresponds to reality, and the truth
is independent of whether we know about it, or what we may think
about it.
This is not to imply that we have a reliable means to discover
this truth, for all we can ever know are our opinions. For
example, in a legal trial, the verdict of the jury may be
incorrect, but even then, it can only be incorrect due to the fact
that it doesn't correspond to the truth. The fact that the jury
endeavors to be correct indicates that they believe that there is
an objective truth which they are seeking to discover.
How does this axiom apply to something as personal as beauty?
Mortimer Adler defines beauty as "that which gives pleasure
upon being beheld." We can't say that an object in one genre
is superior or inferior to an object in another genre; e.g,
neither a Japanese Zen garden nor a European-style Cartesian
garden is better than the other. However, within each genre there
are principles, and therefore an object can be superior or
inferior to another object with the same genre.
Mortimer Adler says that happiness is the measure of goodness and
justice. For example, political oppression, or an unheathy
lifestyle, are objectivey bad because they are logically
inconsistent with long-term happiness.
This objectivism requires Adler to clash with certain viewpoints
which have come to be considered Politically Correct. For
example, is has been popular recently to say that there is no
universal morality for all people, a concept sometimes called
cultural relativism. However, Adler points out, anyone who makes
such a claim, but at the same time speaks disapprovingly of
certain world events, such as genocide or the Soviet invasion of
Afghanistan, would be committing a self-contradiction.
In August and
September of 1983, PBS broadcast Mortimer Adler's six-part TV
series "Six Great Ideas", based on the book. The six
one-hour discussions (truth, beauty, goodness, liberty, equality
and justice) were videotaped in Aspen, Colorado. The participants
came from diverse backgrounds, including a university
administrator, a labor union president, and a diplomat. The
series was hosted by Bill Moyers.
