The Latin term puer aeternus means eternal youth. In Jungian psychology it is used to describe a certain type of man - charming, affectionate, creative and ever in pursuit of his dreams. These are the men who remain adolescent well into their adult years, generally full of life yet strangely draining to those around them. We have worked with them, loved them and watched them wave good-bye. It is impossible to overstate the influence on both men and women of this classic study, originally a series of lectures at the Zurich Jung Institute. It is Jungian psychology in its most down-to-earth voice, telling it like it is so accurately and with such a depth of understanding that it is still much in demand even though it has been out of print for many years. This new edition features a Bibliography and an extensive Index.
