“The search for truth and its investigation are, above all, peculiar to man. Therefore, whenever we are free from necessary business and other concerns we are eager to see or to hear or to learn, considering that the discovery of obscure or wonderful things is necessary for a blessed life.” Marcus Tullius Cicero, On Duties I.13. eds. and trans. M.T. Griffin and E.M. Atkins (Cambridge 1991), pp. 6-7.
