Rationalism assumes that reason gives us all knowledge. It overrides emotion and belief. It also override the senses as the path to truth. It is directly opposed to empiricism.
Reason takes on a mysticism similar to that of the soul, whereby a body is unnecessary. So it is part of the mind-body problem in Western philosophy, culture and thinking.
Sensory knowledge is not perfect. But neither is rational knowledge. Both should be considered inseparable. And both should be considered necessary to any knowledge.
Rationalism and Empiricism should not be considered opposing ideas. There should be a philosophy of Rational Empiricism or Empirical Rationalism.
