incūriōsus

1. Tutus denotes safety objectively, he who actually is safe, like ἀσφαλής; securus (sine cura) subjectively, he who thinks himself safe; hence tutus is used for provident, with reference to foresight; securus is used as a softer expression, for improvident, with reference to the want of foresight. Sen. Ep. 97. Tuta scelera esse possunt, secura non possunt: and 105. The substantive securitas, however, must be used to supply the want of a similar substantive from tutus. 2. Securus, securitas, denote freedom from care and anxiety merely as a state of mind, like ἀμέριμνος, in opp. to sollicitus, Tac. Hist. iv. 58; whereas incuriosus, incuria, denote the want of carefulness and attention, with a practical reference, like heedless, ὀλίγωρος, in opp. to cura. Sen. Ep. 100. Fabianus non erat negligens in oratione, sed securus. (iii. 120.)
