Perperam · Falso · False · Fallaciter

1. Perperam (redupl. of παρά) denotes that which is not true, objectively, with reference to the object, as incorrect; whereas falso, subjectively, in reference to the person, as mistaken. 2. Falso agere has its foundation in error and self-deceit; whereas false and fallaciter happens against better knowledge and conscience; false, through fear and weakness of character; fallaciter, like deceitfully, with the wicked intention of deceiving and betraying. Comp. Tac. Ann. i. 1. Tiberii res . . . ob metum false compositæ sunt, according to Wolf’s reading; comp. with Germ. 36. Inter impotentes et validos falso quiescas. 3. The adjective falsus combines the notions of falso and of the participle falsus, and is distinguished only from fallax. Cic. Phil. xii. 2. Spes falsa et fallax. Tac. Ann. xvi. 33. Specie bonarum falsos et amicitiæ fallaces. (i. 66.)
