 In keeping with Williams’ views, Cécile Laborde (2017, 203) defines integrity as ‘an ideal of congruence between one’s ethical commitments and one’s actions’, and argues (2017, 207) that two tests must be applied to claims (religious or otherwise) for exemptions from laws. These are the thick sincerity of the claimant, and the thin acceptability of the proposed exemption — which must thus be compatible with the basic rights of others. For Lori Watson (2019, 656), no exemptions are permissible which are ‘incompatible with the project of liberal egalitarian justice.’ Giulio Fornaroli (2019, 659) goes further, concluding that ‘the notion of personal integrity is, by itself, unnecessary and possibly detrimental in a theory of justice.’
