JACTATIO; GLORIATIO; OSTENTATIO; VENDITATIO. +Jactatio+ and +gloriatio+ have their foundation in vanity and self-complacency; +jactatio+ is making much ado of one's excellencies and merits, and shows itself in words and actions, with the accessory notion of folly; +gloriatio+ is talking big, proclaiming one's excellencies and merits, with the accessory notion of insolence; whereas +ostentatio+ and +venditatio+ have their foundation in a crafty calculation of the effect to be produced, and a disregard to truth; +ostentatio+ would conceal real emptiness under a false show; +venditatio+ would, by exaggerating one's excellencies, pass them off for greater than they are.
IDONEUS; APTUS. +Idoneus+ denotes a passive, +aptus+ an active fitness for any thing. F. A. Wolf. Or, the _idoneus_ is fitted by his qualifications, and, through outward circumstances, for any particular destination, like the #epitêdeios#; the aptus (from potis, potens), by his worth and adequacy, like #hikanos#. The _idoneus_ is in himself inactive, and suffers himself to be employed for a particular purpose, for which he is qualified; the _aptus_ himself engages in the business, because he is adequate to it. (iii. 276.)
IGNAVIA; INERTIA; SEGNITIA; DESIDIA; SOCORDIA; PIGRITIA. 1. +Ignavia+ denotes the love of idleness, in an +ideal+ sense, inasmuch as the impulse to action distinguishes the more noble from the ordinary man, and gives him an +absolute+ value; in opp. to _industria_, Tac. Ann. xii. 12. xvi. 18; whereas +inertia+ denotes the love of idleness in a _real tangible_ sense, inasmuch as activity makes a man a useful member of society, and gives him a relative value. +Ignavia+ is inherent in the temperament, and has no inclination for action; +inertia+ lies in the character and habits, and has no desire to work. A lazy slave is called _inors_; a person of rank, that passes his time in doing nothing, is _ignavus_. 2. +Segnitia+, +desidia+, +socordia+, and +pigritia+, are the faults of a too easy temperament. +Segnitia+ (from sequi, #oknos#,) wants rousing, or compulsion, and must be conquered, before it resigns its ease, in opp. to _promptus_. Tac. Agr. 21. +Desidia+ (from sedere) lays its hands on its lap, and expects that things will happen of themselves; +socordia+ is susceptible of no lively interest, and neglects its duties from want of thought, like phlegm; +pigritia+ has an antipathy to all motion, and always feels best in a state of absolute bodily rest, like slothfulness. (iv. 212.)
