Book excerpt: Our world’s cultural circles are permeated by the philosophical influences of existentialism and phenomenology. Two contemporary quests to elucidate rationality – took their inspirations from Kierkegaard’s existentialism plumbing the subterranean source of subjective experience and Husserl’s phenomenology focusing on the constitutive aspect of rationality. Yet, both contrary directions mingled readily in common vindication of full reality. In the inquisitive minds (Scheler, Heidegger, Sartre, Stein, Merleau-Ponty, et al.), a fruitful cross-pollination of insights, ideas, approaches, fused in one powerful wave disseminating throughout all domains of thought. Existentialist rejection of ratiocination and speculation together with Husserl’s shift to the genesis of rapproches philosophy and literature (Wahl, Marcel, Berdyaev, Wojtyla, Tischner, etc.), while the foundational underpinnings of language (Wittgenstein, Derrida, etc.) opened the "hidden" behind the "veils" (Sezgin and Dominguez-Rey).
