paragraph_text: Empiricism and rationalism
  
  The debate between empiricism and rationalism centers on the origins of human knowledge. Empiricism emphasizes that sense experience is the primary source of all knowledge. Some empiricists express this view by stating that the mind is a blank slate that only develops ideas about the external world through the sense data it receives from the sensory organs. According to them, the mind can arrive at various additional insights by comparing impressions, combining them, generalizing to arrive at more abstract ideas, and deducing new conclusions from them. Empiricists say that all these mental operations depend on material from the senses and do not function on their own.
  
  Even though rationalists usually accept sense experience as one source of knowledge, they also say that important forms of knowledge come directly from reason without sense experience, like knowledge of mathematical and logical truths. According to some rationalists, the mind possesses inborn ideas which it can access without the help of the senses. Others hold that there is an additional cognitive faculty, sometimes called rational intuition, through which people acquire nonempirical knowledge. Some rationalists limit their discussion to the origin of concepts, saying that the mind relies on inborn categories to understand the world and organize experience.
