Many questions have been raised concerning the logical validity of Aquinas's Fourth Way. Some commentators judge the Fourth Way to be problematic while others find it delightful. In this paper, the Fourth Way is understood as a reflection on what it is to attribute to things around us scalar predicates. Does the Fourth Way not resemble what Wittgenstein observes when speaking about ‘the standard meter’? If so, is the Fourth Way significantly different from what might be called a ‘mystical’ line of thinking? If not, it would be this mystical meaning that is used in the Way with respect to ‘God exists’. How should we understand this mystical meaning? By noting that beauty appears as a response-dependent property and by stressing that in order to attribute it to something we must possess certain virtues. Beauty would then be relative to virtues which are linked to the mystical meaning of ‘God’. Why could such a use, concerning the predicate ‘beautiful’ (even if that is not mentioned in the Fourth Way) not constitute an explanation of ‘what we call God’? This is a question to which the reading of the Fourth Way might lead.
