 The relational event ontology that Whitehead developed in his London period might serve to develop a relational interpretation of quantum mechanics, such as Rovelli’s (cf. supra) or one of the many proposed by Whitehead scholars (cf. Stapp 1993 and 2007, Malin 2001, Hättich 2004, Epperson 2004, Epperson &amp; Zafiris 2013). But then this ontology has to take into account the fact that quantum mechanics suggests that reality is not only relational, but also granular (the results of measuring its changes do not form continuous spectra, but spectra of discrete quanta) and indeterminist (physicists cannot predetermine the result of a measurement; they can only calculate for each of the relevant discrete quanta, that is, for each of the possible results of the measurement, the probability that it becomes the actual result).
