- In philosophy, the brain in a vat (BIV) is a scenario used in a variety of thought experiments intended to draw out certain features of human conceptions of knowledge, reality, truth, mind, consciousness, and meaning. It is a modernized version of René Descartes’s evil demon thought experiment, originated by Gilbert Harman. Found in many science fiction stories, it outlines a scenario in which a mad scientist, machine, or other entity might remove a person’s brain from the body, suspend it in a vat of life-sustaining liquid, and connect its neurons by wires to a supercomputer that would provide it with electrical impulses identical to those a brain normally receives. According to such stories, the computer would then be simulating reality (including appropriate responses to the brain’s own output) and the “disembodied” brain would continue to have perfectly normal conscious experiences, such as those of a person with an embodied brain, without these being related to objects or events in the real world.

Ahmad Shah DURRANI unified the Pashtun tribes and founded Afghanistan in 1747. The country served as a buffer between the British and Russian Empires until it won independence from notional British control in 1919. A brief experiment in increased democracy ended in a 1973 coup and a 1978 communist countercoup. The Soviet Union invaded in 1979 to support the tottering Afghan communist regime, touching off a long and destructive war. Internationally supported anti-communist mujahidin rebels forced the USSR to withdraw in 1989. A series of subsequent civil wars saw Kabul finally fall in 1996 to the Taliban, a hardline Pakistani-sponsored movement. Following the 11 September 2001 terrorist attacks, a US and Allied military action toppled the Taliban for sheltering Usama BIN LADIN.
