Liberalismus, Socialismus und christliche Gesellschaftsordnug/Liberalism, Socialism and Christian Social Order Book 3: Private Property as a Social Institution

First published in 1900, Das Privateigentum als sociale Institution, was Pesch's work on the right of private ownership. Pesch's priestly training in the Aristotelian-Thomistic was reflected in this book as he stood in opposition to the absolutistic notion which had resurfaced in the modern world under the influence of both the Enlightenment and socialist thought. The right of private ownership became one of the pillars in Pesch's social order which was subsequently adopted in later Catholic social thought.
