[In order to counter the dominance of subjectivity in modern German philosophy since Kant, the young Hans Urs von Balthasar appealed to the theocentric epistemology of Gregory of Nyssa. By means of a study of Balthasar's Présence et Pensée: Essai sur la philosophie religieuse de Grégoire de Nysse, the purpose of this essay will be to elucidate Balthasar's interpretation of the meaning and orientation of thought according to Gregory of Nyssa's epistemology. After an initial presentation of Balthasar's contention that for Gregory of Nyssa God qua Being (to einai) serves as the constitutive source of thought and, therefore, the necessary orientation for any philosophical reckoning of the meaning of thought, the following issues are addressed: 1.) The meaning of thought as erotic and egressive, 2.) the interpretation of imago dei in relation to thought, 3.) the Incarnation and the ultimate horizon of thought.]
