We have previously devoted a lengthy study to the subject of spiritual maladies. As a result, we will limit ourselves in this work to merely recalling the analysis of the passions of acedia and sadness—their links with the various forms of depression are quite obvious and, in recent years, have attracted the attention of some psychiatrists who have shown themselves quite sensitive to the depth, richness and wisdom of Patristic analysis.

These last mentioned illnesses have an exemplary value. All the more so as symptoms of anxiety and depression afflict over two hundred million individuals, who most often receive only chemical treatment for their illness. Undoubtedly some of these are organic in origin and, as such, this therapy is justified. However, most of them, as is generally admitted, are suffering from what is currently called ‘mal de vivre’ (feeling lousy’). In other words they suffer from existential problems which standard psychiatry remains totally incapable of treating. It is obvious that these problems to a great extent relate to the spiritual sphere as envisioned by the Fathers whose nosology and therapeutic techniques would appear to be most pertinent, for despite the fact that both time and social context are different, they touch upon universal dimensions of human existence, upon difficulties that afflict everyone who desires to find a meaning for existence and to harmonize their interior life; individuals who wish to conform their activities to values whose disappearance, as many psychiatrists and psychologists admit, leads to the increase of mental problems, especially anxiety and depression.
