Abstract: ‘The guarantee’, or the claim that any use of I is logically guaranteed against reference-failure as a matter of the meaning of the term, is a myth. If security is a semantic truth, I cannot be a genuinely singular referring term. There is no argument for ‘the guarantee’, which is independent of ‘rule theory’ and ‘independence’. Even professed advocates of ‘the guarantee’ turn out to defend a non-semantic explanation of security.

Keywords: the guarantee, reference-failure, security, logical guarantee, semantic truth, pragmatic explanation, Anscombe, Strawson,
