An absolute must read for aspiring psychologists or those simply wanting a deeper understanding of mental health.
By having its basis in Thomistic philosophy, the perennial philosophy, it builds a solid and holistic framework for the proper understanding of what constitutes mental health and it's inverse, mental illness. The book avoids the pitfalls of modern psychology, which is largely based on materialistic philosophy and therefore doomed to not only be insufficient but sometimes even detrimental to true mental health.
In the end, only a psychology which takes into account the true ontological structure of man, his relation to God, the reality of sin and it's subsequent effect on mental health, and the indispensable importance of virtue as opposed to vice in regards to mental health will have any hope at successfully treating those with mental illness.
