邏輯上、物理上與法律上不能 Logical, Physical and Legal Impossibilities

邏輯上不能者，物理上不能。	Logical impossibility implies physical impossibility.
邏輯上不能或物理上不能者，未必法律上不能。	Logical impossibility or physical impossibility do not imply legal impossibility.
但以邏輯上不能或物理上不能為法律上所能者，即為災禍。	However, it will be a disaster when we think a law possibly effective to a thing that is logically impossible or physically impossible.
