'Kwintet metafizyczny' (Metaphysical Quintet) includes five essays in which professor Barbara Skarga, the eminent researcher of modern and contemporary philosophy, and philosopher herself, confesses her philosophical credo. The leitmotif of the book is the key concept of the 'origin' in classical Western philosophy, and its main subject - metaphysicality and metaphysical thinking. By reflecting upon the origin and primordiality of thinking, upon the origin of time, evil, experience and metaphysicality itself, by discussing with witnesses of the deepest and crucial metaphysical experiences: Plato, Plotinus, Descartes, Immanuel Kant, Martin Heidegger, Edmund Husserl, Emmanuel Levinas, B. Skarga shows her own way to the origin of thinking where metaphysicality is born. She discovers these origins not in the human finitude, as Heidegger, nor merely in infinity, as Levinas, but in the dialectic between finitude and infinity.
