Donald Hoffman states that when it comes to a brain or a volleyball, “if you don’t look, it’s not there”. He also believes that “a volleyball no more has a position or momentum when it’s not observed than does an electron”. All this is basically a 21st-century update of Bishop Berkeley’s 18th-century idealism (as Hoffman more or less admits in various places).
