Philip of the Blessed Trinity on Mystical Knowledge
Peculiar Kinds of Species

This study concerns the theory of mystical knowledge advanced by the practically unknown seventeenth-century Carmelite author Philip of the Blessed Trinity in his work Summa Theologiae Mysticae. Philip introduces “a new kind” of spiritual species representing the intellectibilia to describe how individuals are granted mystical knowledge, and in doing so distinguishes between three kinds of species. Philip’s notion of mystical knowledge is closely related to the topic of contemplation and is profoundly influenced by The Interior Castle of St. Teresa of Avila. The analysis presented here, therefore, represents an original contribution to the ongoing scholarly study of species, (mystical) knowledge, and Teresian spirituality.
