This article deals with the development of Jaroslava Pešková's thinking about practice and ethics. In philosophy of creative marxists thinkers in sixties, there is an important common horizon of the "governability of history" by human subjective practical activity.
This horizon is problematized by Jaroslava Pešková, who is following Jan Patocka's phenomenological critique of Karel Kosík's Dialectics of the Concrete. The practice is not some movement within the substantial form, but presupposing the relation to its meaning, so the form-content relation is not to take metaphysically as some "3rd person fact", but is conditioned by the original relation of human being to its being.
