Does the category "Philosophy" just mean that you can ask anything as long as it doesn't make common sense?

No, philosophy have many other branches, viz. philosophy of religion, epistemology and metaphysics. Especially in the philosophy of religion, or theology, we will always ask old questions like 'Where is God?', 'Is there an afterlife? and 'Do you believe in reincarnation?', and we will give our new answers (but the idea is the same as the antecedents). When we bring up old questions, that is common sense, since old questions have been debated for centuries.

"Philosophy, which brought us to the Absurd, can carry us through it as well?"

R. Solomon

common sense???? --> collection of prejudices acquired by the age 18. You should read some more books. Philosophy is the end-station. It is the most durable thing I ever approached.

This amuses me. :)

This category means you ask something that you want to find a deeper meaning for, and you hope someone else can shed some light on your darkened brain.

Lacking common sense, enough?

Hope I helped.

people who have common sense use this

but still people put stupid questions like ...........to make others think that philosophy is used to ask anything that has no common sense

Not in my dictionary. It is a speciality

Some people don't take this seriously, others do.
