Quantum philosophy

Quantum philosophy was a branch of philosophy which dealt with, for example, the morality of transmats. Charley Pollard felt there was "something sinister" about transmat technology, as they disassembled things one nanometre at a time and then reassembled them. When she told the Eighth Doctor, "It's like killing something in one place and bringing it to life in another," the Doctor muttered something about Charley one day becoming a brilliant quantum philosopher, and made her get in the transmat anyway.
