  According to Reinach, material a priori states of affairs and essences exist independently of the contingent minds that may apprehend them and of the individual objects that may instantiate them. Such instantiation will however bring in its wake a series of concrete associations with other entities. Thus in writing about the legal entities (such as rights and obligations) that are grounded in the essence of promising, Reinach notes that when such legal entities exist, they become “intimately interwoven with the rest of the natural world, with all the experiencing of persons who perform acts, with their feelings and wishes, their desires and intentions, their expectations and fears, etc.” (1913, p. 130)
