The article consists of a brief and introductory analysis of the model of introspection as the source of cognition of natural law which is based on personalist anthropology. The model of such cognition stems mainly from the phenomenological anthropology of Karol Wojtyła, but is not restricted to his philosophy. The author strongly believes that the Wojtyła’s “Person and Act”, published in 1969, opened a new era in Christian philosophy as it shows the way to overcome the subjectivist crisis of the Western philosophy and it enables us to rebuild the classical philosophy, using phenomenological and personalist anthropology. This vision also embraces human subjectivity without losing the objective character of natural law. In doing so, it contributes to enriching the Thomistic concept of natural law. Transcendence and integration of a person into a human act (actus humanus) – as Wojtyła sees it – becomes a fundamental condition of proper human cognition and – what is more important – of proper human action.
