You can use Aristotle's subset of logic in exactly the same way that you
would use OWL or any other DL. It is the most widely used subset of any
of them. But it is very easy to learn, and it can be written in just
four simple sentence patterns in English or any other language. (04)

That's true because it's impossible to implement any practical
application without using Turing-complete languages, which can
express undecidable programs. (07)
Tim B-L recognized that point in his DAML proposal in 2000, but the
"decidability thought police" killed many useful languages, such as
SWRL, RuleML, and others, because they were undecidable. (08)
As a result, it's impossible to implement a complete application with
just the SW-approved tools. Every developer has to supplement them
with undecidable languages that are not on the approved list. (09)

I agree. (013)
When you get a million data items that were produced by more than one
person using more than one computer program, you can be certain that
you're comparing apples, oranges, walnuts, and sauerkraut. (014)
When you get to 50 billion, they will break down into many different
subgroups, each of which might be useful in some context from some
perspective. But there is no single reasoning method that could
meaningfully deal with all of them. (015)
