In Schelling there is an interaction between thinking (activity) and feeling or sensing(receptivity), making up the elements of differential thinking. Tillich’s aesthetics and essentialization might be understood in the light of the differential view. The first part of the paper discusses Tillich’sessentialization in the light of the differential thinking and in relation to Schelling’s potentialization. The second part of the paper discusses the conception of the synthesis ofpersonality in Tillich and in Kierkegaard and its expressions in recent new aesthetics.The synthesis of personality is central in essentialization: the synthesis is formed in the interplay between positive and negative elements; synthesis is truth done. The paper also discusses art as "truth done" and it lifts up examples in contemporary art in which the synthesis of personality and the expressiveness of ethics and truth are explicated.
