Only 2 types of statements exist: Synthetic & Analytic. Since moral statements cannot be defined (‘unanalysable’) they are valueless.
Hume – Ethical statements are based on values not facts.
Foucault – Morality is historically contingent.
Karol – Ethical demands and stances grow out of human encounters. It is through encountering good and bad that we uncover morality and the need to be moral. Ethical statements do not require scientific justification, but instead the human experience.
Mel Thompson might insist emotivism trivialises moral laws, but emotivists are not directing people in how to live their lives, only assessing if morality exists. Perhaps a dislike of murder is enough.
Accounts for a variety of beliefs based on individuality, but also culture environment and identity.
Emotivism sets the bar too high by arguing that since I cannot prove something it becomes futile. (eg. I cannot prove paedophilia is wrong, though I can give reasons as to why it is wrong – detrimental psychological effects, violation of human rights etc.)
Emotivism means morality is relative. Therefore, racists are correct in saying that racism is good.
Mel Thompson: “you cannot reduce morality to a set of cheers and boos”. Ethics is trivialised; laws such as “do not murder” appear no-more important than claiming, “I do not like sweets”.
Devalues laws – if we are not basing our laws of off good and bad, then why have them? Why are they so crucial?
Meaning is not only relevant to what we can prove. Whilst 1+1=2 is meaningful and accurate, something such as life after death can still have meaning to theists, despite it being unverifiable.
Karl Poppers Problem of Induction: it is asking how to justify theories given they cannot be justified by induction. Popper argued that justification is not needed at all, and seeking justification "begs for an authoritarian answer".
Waismann criticised the vagueness of the verification principle.
Hilary Putnam criticized the positivism distinction between observational and theoretical terms
