text: **Type-C Materialism**
  Type-C materialists acknowledge a distinction between knowledge and experience[98] without asserting a 
  more complete explanation for the experiential phenomenon. One taking this view would admit that there 
  is an explanatory gap for which no answer to date may be satisfactory, but trust that inevitably the gap 
  will be closed.[52] This is described by analogy to progression in other areas of science, such as mass- 
  energy equivalence which would have been unfathomable in ancient times,[52] abiogenesis which was 
  once considered paradoxical from an evolutionary framework,[99][98] or a suspected future theory of 
  everything combining relativity and quantum mechanics. Similarly, type-C materialism posits that the 
  problem of consciousness is a consequence of our ignorance[71][100] but just as resolvable as any other 
  question in neuroscience. 
  
  Because 
  type-C materialism does not 
  presuppose[101] the descriptive question, for instance that there is any self-consciousness, wakefulness, or 
  even sentience[102] in a rock. Principally, the basis for the argument arises from the apparently high 
  correlation of consciousness with living brain tissue,[103] thereby rejecting panpsychism[101] without 
  explicitly formulating physical causation. More specifically this position denies the existence of 
  philosophical zombies[64] for which there is an absence of data and no proposed method of 
  testing.[104][105] Whether via the inconceivability or actual nonexistence of zombies, a contradiction is 
  exposed nullifying the premise of the consciousness problem's "hardness". 
  
  the explanatory question of consciousness  is evaded,
