Thomas Aquinas

“ Yet, since the object of hope is good, to which the appetite tends naturally, and which it shuns, not naturally but only on account of some supervening obstacle, it follows that, more directly, hope gives birth to joy, while on the contrary despair is born of sorrow. ”

“ In every mortal sin there is, in some way, aversion from the immutable good, and conversion to a mutable good, but not always in the same way. Because, since the theological virtues have God for their object, the sins which are contrary to them, such as hatred of God, despair and unbelief, consist principally in aversion from the immutable good; but, consequently, they imply conversion to a mutable good, in so far as the soul that is a deserter from God, must necessarily turn to other things. ”

“ Now, the fact that spiritual goods taste good to us no more, or seem to be goods of no great account, is chiefly due to our affections being infected with the love of bodily pleasures, among which, sexual pleasures hold the first place: for the love of those pleasures leads man to have a distaste for spiritual things, and not to hope for them as arduous goods. In this way despair is caused by lust. ”

“ Further, in the sin of despair there is nothing but inordinate aversion from God: whereas in other sins there is not only inordinate aversion from God, but also an inordinate conversion. Therefore the sin of despair is not more but less grave than other sins. ”

“ Therefore, just as the movement of hope, which is in conformity with the true opinion, is praiseworthy and virtuous, so the contrary movement of despair, which is in conformity with the false opinion about God, is vicious and sinful. ”

“ If anyone were to judge, in universal, that God's mercy is not infinite, he would be an unbeliever. But he who despairs judges not thus, but that, for him in that state, on account of some particular disposition, there is no hope of the Divine mercy. ”

“ If, however, despair be compared to the other two sins from our point of view, then despair is more dangerous, since hope withdraws us from evils and induces us to seek for good things, so that when hope is given up, men rush headlong into sin, and are drawn away from good works. ”

“ Secondly, a thing proceeds from a virtue indirectly, or is occasioned by a virtue, and in this way nothing hinders a sin proceeding from a virtue: thus sometimes men pride themselves of their virtues, according to Augustine (Ep. ccxi) : "Pride lies in wait for good works that they may die." In this way fear of God or horror of one's own sins may lead to despair, in so far as man makes evil use of those good things, by allowing them to be an occasion of despair. ”

“ Now the true opinion of the intellect about God is that from Him comes salvation to mankind, and pardon to sinners, according to Ezech. 18:23, "I desire not the death of the sinner, but that he should be converted, and live" [*Vulg.: 'Is it My will that a sinner should die . . . and not that he should be converted and live?' Cf. Ezech. 33:11] : while it is a false opinion that He refuses pardon to the repentant sinner, or that He does not turn sinners to Himself by sanctifying grace. ”

“ This very neglect to consider the Divine favors arises from sloth. For when a man is influenced by a certain passion he considers chiefly the things which pertain to that passion: so that a man who is full of sorrow does not easily think of great and joyful things, but only of sad things, unless by a great effort he turn his thoughts away from sadness. ”

“ Now it may happen that a man, while having a right opinion in the universal, is not rightly disposed as to his appetitive movement, his estimate being corrupted in a particular matter, because, in order to pass from the universal opinion to the appetite for a particular thing, it is necessary to have a particular estimate (De Anima iii, 2) , just as it is impossible to infer a particular conclusion from an universal proposition, except through the holding of a particular proposition. ”
