In the Preface to Critique of Political Economy in 1859, Marx revised his previous view and changed the determinism of material production to the theory of restriction of material production. The reason for restriction rather than determinism lies in material production or horizontal or vertical facet in other areas, other areas have their own special laws. Only when stepping into these special laws of material production can such theory have an impact. However, because of the arbitrariness of his use of words, the decisive role of the economy in the text after 1859 should be understood as constraints, otherwise it would deviate from Marx's initial purpose.
