Thought generally 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. Similar concepts include cognition, sentience, consciousness, and imagination.[1] Because thought underlies almost all human actions and interactions, understanding its physical and metaphysical origins, processes, and effects has been a longstanding goal of many academic disciplines including, among others, biology, philosophy, psychology, and sociology.
Thinking allows beings to make sense of or model the world in different ways, and to represent or interpret it in ways that are significant to them, or which accord with their needs, attachments, objectives, plans, commitments, ends and desires.
The word comes from Old english þoht, or geþoht, from stem of þencan "to conceive of in the mind, consider".[2]
In common language, the word to think covers numerous and diverse psychological activities. It often refers merely to the act of being conscious of something, especially if that thing is outside the immediate environment ("It made me think of my grandmother"). It is sometimes a synonym for "tending to believe," especially with less than full confidence ("I think that it will rain, but I am not sure"). At other times it denotes the degree of attentiveness ("I did it without thinking"). Many other mental activitiesmany of which may shade into each othercan be covered by the word, such as interpreting, evaluating, imagining, planning, and remembering.
In common usage, "thought" is often attributed to animals, machines, other non-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.
Little is written about the actual content of thoughts. It would seem we do not think in complete sentences. We think fragments, ideas embodied in words. We don't think "I mailed the package to my sister this morning", we think "mailed package sister morning". If we're reading a book our thoughts include the story line and our reflections on the story line. But our thoughts can contain only one idea at a time, so if the plot is "hero runs after murderer" and our reflection is "he was foolish to trust the villain", our thought is something like "hero foolish trust run after murderer villain".[citation needed]

The phenomenology movement in philosophy saw a radical change in the way in which we understand thought. Martin Heidegger's phenomenological analyses of the existential structure of man in Being and Time cast new light on the issue of thinking, unsettling traditional cognitive or rational interpretations of man which affect the way we understand thought. The notion of the fundamental role of non-cognitive understanding in rendering possible thematic consciousness informed the discussion surrounding Artificial Intelligence during the 1970s and 1980s.
