“To learn in order to know is scandalous curiosity.”
Sunt qui scire volunt tantum, ut sciant, et turpis curiositas est.
Translation from Etienne Gilson, The Mystical Theology of St. Bernard
Then you have some people who wish to know for the sake of knowing, and that is scandalous curiosity. (Translation from J. Van Herwaarden, Between Saint James and Erasmus: Studies in Late-Medieval Religious Life)
