The examination and comparison of the philosophy of the ordinary of the two major philosophers of the twentieth century, late analytic L. Wittgenstein and early phenomenologist M. Heidegger, are presented in this paper. As the method of study J. L. Austin’s speech action theory was chosen. According to this theory, the philosophies of Wittgenstein and Heidegger are focused on the practicality of the human. The paper demonstrates that Heidegger’s concept of handiness, due to which E. Husserl’s concept of intentionality is re-interpreted on the basis of philosophy of the human practice, correlates with Wittgenstein’s conception of certainty.
