Most discussions about deity in the current theism/scientism debate are
replete with Euro-American myopic views about Western philosophical-theological
history and terms. This is particularly true about monotheism’s incipient
onto-theology (as Heidegger uses that term).
The idea that deity/god transcends both essence (hyperousia) and substance
(hypostasis) is either unknown or unrecognizable in this debate by both sides.
A short synopsis about Heidegger’s “OntoTheology”:
For Heidegger, OntoTheology contributes to the oblivion or forgetfulness of
Being. Indeed "metaphysics is Onto-Theo-logy," and Western metaphysics "since
the beginning with the Greeks has eminently been both Ontology and theology."
The problem with this intermixing of ontology and theology according to
Heidegger's analysis, and the reason why Heidegger and his successors sought to
overcome it, is at least twofold.
First, by linking the philosophical with the theological, and vice versa, the
distinctiveness of each respective discourse is clouded over. As such, the
nature of philosophy as a factually unknown and structurally unknowable path of
thought is restricted by an economy of faith. Likewise, with theology, as the
science of faith, theology at its best testifies to the irreducible mystery of
its source in revelation and to the unapproachable and incomprehensible aim of
its desire in God. However, once theology becomes Onto-Theological that
mysterious source and incomprehensible aim are reduced to the order of beings.
Second, and on a more fundamental level, the OntoTheological problem is part
and parcel of the overall degeneration of Western thought and the consequent
troubles of Western technological culture. The problem, in a nutshell, is the
human desire for mastery and OntoTheology contributes to this by presuming
knowledge regarding the "first cause" of philosophy and the "highest being" of
theology.
According to Merold Westphal, Heidegger has three main objections to
onto-theology:
First, it deprives the world of its mystery. Second, it gives us a God not
worthy of worship.
In a famous passage, Heidegger complains that before the causa sui (a name for
the God of onto-theology that emphasizes the need for an explainer that doesn’t
need to be explained) no one would be tempted to pray or to sacrifice and that
this God evokes neither awe nor music and dance. Onto-theology is hostile to
piety.
"Third, having deprived the world of both its mystery and of a God worthy of
worship, onto-theology opens the way for the unfettered self-assertion of the
will to power in the form of modernity, namely the quest of science and
technology to have everything at human disposal. This is the ultimate hubris of
western humanity, in which, under the banner of modernity, it arrogates to
itself the place of Plato’s Good and the Christian God. Heidegger describes
this self-coronation as an attack, an assault, an uprising, an insurrection."
