Abstract: The kernel of Morris' view of sign is to regard semiosis as an action involving relations between two "vehicle" and two "others": "sign vehicle" refers to "designatum"; "sign vehicle" causes "interpretant". The scope of the two "others" are too narrow for the view of sign to encompass various kinds of signs; the relationship between "sign vehicle" and "interpretant" is not causal by nature; "designatum" and "interpretant" never get both involved in a semiosis. Morris' view of sign, inheriting Peirce's triadic view of sign and behaviorism, fails to meet Moriis' expectation.
