mine whether an attempt at defining âgoodâ is correct and not a concealed assignment is what Moore called the âopen question argument.â Moore proposed that if âgoodnessâ is a natural property, then there is some correct explanation of which natural property it is. For example, maybe âgoodnessâ is the same property as âpleasantnessâ, or the same property as being âdesirableâ. Further, a correct property must be identified to fill in an identity statement of the form âgoodness = __________â, or, âwhat is good is _________â. This kind of identity statement can be correct only if both terms on either side of the identity sign are synonyms for proficient speakers who understand both terms. Synonymy of the two terms is then tested through substitution of a term. Mooreâs idea is that substitution of synonyms for one another preserves the original proposition that a sentence expresses. For example, using the sentence: âwhat is good is pleasant.â For this to pass Mooreâs test, the sentence would have to express the same thing as âwhat is pleasant is pleasant.â Moore believed it was obvious that these two sentences do not express the same proposition. In thinking that what is good is pleasant, Moore thought one is not only thinking that what is pleasant is pleasant. According to Moore, there is an âopen questionâ as to whether what is good is pleasant, and it can be understood when someone doubts the generated statement. However, there is no âopen questionâ as to whether what is pleasant is pleasant, because this analytic truth cannot be doubted. Therefore, Moore thought that no substitution will pass the test. Therefore, there is no natural property of âgoodnessâ. In other words, according to Moore and his open question argument, âgoodnessâ is a non-nat>
