Jacques Maritain - Metaphysics and Epistemology

Metaphysics and Epistemology

Maritain's philosophy is based on the view that metaphysics is prior to epistemology. Being is first apprehended implicitly in sense experience, and is known in two ways. First, being is known reflexively by abstraction from sense experience. One experiences a particular being, e.g. a cup, a dog, etc. and through reflexion ("bending back") on the judgement, e.g. "this is a dog", one recognizes that the object in question is an existent. Second, in light of attaining being reflexively through apprehension of sense experience one may arrive at what Maritain calls "an Intuition of Being". For Maritain this is the point of departure for metaphysics; without the intuition of being one cannot be a metaphysician at all. The intuition of being involves rising to the apprehension of ens secundum quod est ens (being insofar as it is a being). In Existence and the Existent he explains:

"It is being, attained or perceived at the summit of an abstractive intellection, of an eidetic or intensive visualization which owes its purity and power of illumination only to the fact that the intellect, one day, was stirred to its depths and trans-illuminated by the impact of the act of existing apprehended in things, and because it was quickened to the point of receiving this act, or hearkening to it, within itself, in the intelligible and super-intelligible integrity of the tone particular to it." (p. 20)

In view of this priority given to metaphysics, Maritain advocates an epistemology he calls "Critical Realism". Maritain's epistemology is not "critical" in Kant's sense, which held that one could only know anything after undertaking a thorough critique of one's cognitive abilities. Rather, it is critical in the sense that it is not a naive or non-philosophical realism, but one that is defended by way of reason. Against Kant's critical project Maritain argues that epistemology is reflexive; you can only defend a theory of knowledge in light of knowledge you have already attained. Consequently, the critical question is not the question of modern philosophy – how do we pass from what is perceived to what is. Rather, "Since the mind, from the very start, reveals itself as warranted in its certitude by things and measured by an esse independent of itself, how are we to judge if, how, on what conditions, and to what extent it is so both in principle and in the various moments of knowledge?"

In contrast idealism inevitably ends up in contradiction, since it does not recognize the universal scope of the first principles of identity, contradiction, and finality. These become merely laws of thought or language, but not of being, which opens the way to contradictions being instantiated in reality.

Maritain's metaphysics ascends from this account of being to a critique of the philosophical aspects of modern science, through analogy to an account of the existence and nature of God as it is known philosophically and through mystical experience.
