Does rational thinking avoid dogma and enhance our wisdom?
There are 3 kinds of knowledge.


knowledge based on thinking (cintā-mayā-paññā). Rational thinking comes under this.
knowledge gained by learning from others (suta-mayā-paññā)
knowledge based on mental development or meditation (bhāvanā-mayā-paññā)


Only the third kind of knowledge leads one to freedom from suffering. One can never attain enlightenment by thinking up theories.
