Yakov Frenkel Quote

One has to stress once again, that the mechanical world view and psychophysical interpretation accompanying it are based not on the instructions of the philosophizing mind, but on the clear and accurate facts discovered by experiment and observation; and in the cases of non-correspondence (very rare, fortunately) between the requirements of the mind and the facts, reason must adjust to the facts, and not vice versa.
