text: **Machine consciousness, sentience, and mind**
  
  The philosophy of mind does not know whether a machine can have a mind, consciousness and mental 
  states, in the same sense that human beings do. This issue considers the internal experiences of the 
  machine, rather than its external behavior. Mainstream AI research considers this issue irrelevant because 
  it does not affect the goals of the field: to build machines that can solve problems using intelligence. 
  Russell and Norvig add that "[t]he additional project of making a machine conscious in exactly the way 
  humans are is not one that we are equipped to take on."[380] However, the question has become central to 
  the philosophy of mind. It is also typically the central question at issue in artificial intelligence in fiction.
