He cofounded the journal Civiltà Cattolica in 1850 and wrote for it for twelve years. He was particularly concerned with the problems arising from the industrial revolution. He reasoned that whereas different opinions on the natural sciences have no effect on nature, unclear metaphysical ideas about humanity and society can lead to social chaos.
After the social revolutions of 1848, the Church decided to enter the conflict raging between the laissez-faire liberal capitalists and the socialists.
Up until then, the Church relied primarily on evangelical charitable activities. In 1850, Taparelli was granted permission by Pope Pius IX to co-found Civiltà Cattolica with Carlo Maria Curci.
In particular, he attacked the tendency to separate morality from positive law, and also the “heterodox spirit” of unconstrained freedom of conscience which destroyed the unity of society. His major ideas include sociality and subsidiarity.
Each level of society has both rights and duties which should be recognized and supported.
All levels of society should cooperate rationally and not resort to competition and conflict.
