Thought refers to any mental or intellectual activity involving an individual's subjective consciousness. It can refer either to the act of thinking or the resulting ideas or arrangements of ideas. Simnon-human objects, and phenomena. The exact meaning of such usage varies as well. The attribution of thought or thought processes to non-human objects and phenomena (especially computers) could be considered anthropomorphism, though such categorizations have been contested by such computer scientists as Alan Turing (see Computing Machinery and Intelligence). As regards animals, to what extent different animals think depends on the exact definition of the word that is given, so it may be taken literally or regarded as anthropomorphic.
