Philo Judaeus De Virtutibus 30

[30] And, secondly, that men might not be warring with their bodies while their souls were far from the battle; for it is impossible but that the minds of men in such a condition as has been described above must be held back and kept on the stretch, from a desire to enjoy the things from which they have been torn away. For as men who are hungry or thirsty, if they only get a sight of anything to eat or to drink, pursue it and run after it without ever turning aside in their eagerness to reach it, so also men who have laboured to obtain a legitimate wife, or a house, or the possession of a farm, and who in their hopes believe that the time for their enjoyment of each of these objects is all but arrived, if they are then deprived of that enjoyment, resist, so that though they may be present in body elsewhere, they are not present with the better part of their soul, by which it is that men succeed or fail.
