Whitehead's thought continues to attract attention in mathematics and metaphysics, but few have recognized with Roland Faber, the deeply mystical dimensions of his philosophy. ""If you like to phrase it so,"" Whitehead states, ""philosophy is mystical. For mysticism is direct insight into depths as yet unspoken."" Where, however, do these unspoken depths speak in Whitehead, and what are their associated themes in his philosophy?
For the first time, Depths As Yet Unspoken gathers together Faber's most compelling writings on Whitehead's mutually immanent themes of mysticism, multiplicity, and divinity. In dialogue with a diversity of voices, from process philosophers and theologians, to mystical and poststructuralist thinkers, Faber creatively articulates Whitehead's ""theopoetic"" process cosmogony in its relevance to metaphysics, cosmology, everyday experience, religious pluralism, and interreligious violence, spirituality, and longstanding concerns of the theological tradition, including creation, the Trinity, revelation, religious experience, and divine mystery.
Although Whitehead's mystical inclinations may not be obvious at first, they in fact constitute the apophatic backdrop to his entire philosophical corpus. Through Faber's work, Whitehead's philosophy is revealed to be nothing short of a remarkable endeavor to speak to the unfathomable depth of things.
