>most empiricists believe that mathematicians have knowledge not based on sense experience. Even the knowledge that 1+1=2 comes from sensing objects in the world. If you'd never seen more than 1 thing ever you would have no sense experience to base your conceptual framework of addition on. All knowledge -mathematical or otherwise- can be traced back to sense experience. Your ability to reason mathematically comes from your experience of the world and from your experience of your own thoughts. Intuition is fundamentally a sensory experience.
