BOUQUILLON, THOMAS-JOSEPH. - Belgian moralist, born at Warne ton on 16 May 1840, died in Brussels on 5 November 1902. After graduating from the Gregorian University, he spent his entire life teaching moral theology, at Bruges (1867-77), Lille (1877-1885), and Washington (1889-1902).
He wrote: *Institutiones Theologiae moralis fundamentalis* (Bruges 1873, 3rd ed. 1903); *De virtutibus theologicis* (ibid. 1875, 2nd ed. 1890); *De virtute religionis* (2 vols., ibid. 1880). He also addressed the problem of compulsory education imposed or to be imposed by the state: *Education, to whom does it belong?* (Baltimore 1891), which provoked controversy and contradictions, against which he defended himself with further publications (cf. S. Brandi, in *La Civiltà Cattolica*, 15th series, I [1892, 1], pp. 82-92). Yet his name is linked to moral theology, which he elevated to a modern scientific level through clarity of exposition, sound doctrine, profound discussion, uncommon erudition, and social awareness.
