Keller is unusually wide-ranging, but her engagements are not scattershot; they cluster around process thought, feminist theory, continental philosophy, political theology, and the sciences. Below is a selective but representative map of thinkers she has engaged substantively (not just name-checked), with brief notes on how they function in her work.

---

Process philosophy & metaphysics

• Alfred North Whitehead – Central interlocutor. Keller develops a feminist, ecological, and apophatic rereading of process metaphysics.

• Charles Hartshorne – Engaged critically; she pushes beyond his more classical theism.

• Isabelle Stengers – Important for cosmopolitics, speculative responsibility, and resisting totalizing explanations.

• Gilles Deleuze – Especially around becoming, multiplicity, and non-substantial ontology (often filtered through Whitehead).

Theology & negative theology

• Meister Eckhart – Key for apophatic theology, non-sovereign divinity, and unknowing.

• Pseudo-Dionysius – Foundational for Keller’s cloud imagery and theology of the impossible.

• Nicholas of Cusa – Coincidence of opposites; learned ignorance.

• Paul Tillich – Ontological theology and the question of ultimate concern.

• Jürgen Moltmann – Engaged and critiqued on political theology and eschatology.

Feminist & critical theory

• Judith Butler – On vulnerability, normativity, non-sovereign subjectivity (as discussed).

• Donna Haraway – Strong resonance around situated knowledge, entanglement, and response-ability.

• Luce Irigaray – Sexual difference, relational ontology, critique of phallocentrism.

• Julia Kristeva – Abjection, negativity, and the semiotic.

• Hélène Cixous – Écriture féminine and theopoetics.

Continental philosophy

• Jacques Derrida – Différance, aporia, undecidability; especially in Cloud of the Impossible.

• Emmanuel Levinas – Ethics of alterity, though Keller resists his transcendence of world.

• Hannah Arendt – On plurality, natality, and worldliness (often in political-theological contexts).

• Giorgio Agamben – Engaged critically, especially around messianicity and potentiality.

Political theology & ethics

• Walter Benjamin – Weak messianism, interruption, history.

• Carl Schmitt – As a foil; sovereignty and decisionism.

• Johann Baptist Metz – Political theology and dangerous memory.

Science, ecology & cosmology

• Ilya Prigogine – Chaos, indeterminacy, non-equilibrium systems.

• Karen Barad – Quantum entanglement, intra-action (especially important for Keller’s later work).

• Bruno Latour – Actor-network theory, Gaia, nonmodernity.

• Teilhard de Chardin – Engaged cautiously, often critically.

How to read this list (important)

Keller does not treat these thinkers as authorities to be synthesized cleanly. She engages them theopoetically—through resonance, diffraction, and tension. That’s why, from your angle, her work can feel simultaneously rich and risky: critique is often folded into cosmological generosity rather than held apart.

If you want, next we could:

• Contrast Keller’s engagement style with Agamben’s use of examples, or

• Identify which of these figures most strongly resist being absorbed into her entanglement metaphysics.
