Per Amica Silentia Lunae - W.B. Yeats

Summary

Per Amica Silentia Lunae (Latin for "Through the Friendly Silences of the Moon") is a complex prose work by W.B. Yeats, published in 1918. It is not a narrative with a traditional plot but rather a philosophical and mystical exploration of the self, the spiritual world, and artistic inspiration. The book delves into Yeats's theories of the "Daimon" (a spiritual guide or adversary), the "Mask" or "Anti-self" (a deliberate construct to achieve wholeness), and the "Anima Mundi" (World Soul or collective unconscious). Yeats seeks to understand the source of poetic genius and the nature of reality beyond the material, drawing on his deep engagement with occultism, Neoplatonism, and various esoteric traditions. It is a deeply personal meditation on his artistic and spiritual journey, reflecting his belief in spirit communication and the cyclical nature of existence.

Book Sections

Section: Anima Hominis

This first part, meaning "The Soul of Man," focuses on the individual's inner life, the artist's struggle, and the philosophical concepts that define one's personality and destiny. Yeats introduces his crucial idea of the "Mask" or "Anti-self." He posits that true creativity and self-realization come not from expressing one's natural self, but from embracing and consciously constructing an opposite self—a challenging, often antagonistic, ideal that forces the individual beyond their inherent limitations. This "Mask" is not a disguise but a path to genuine identity and artistic power. He also introduces the concept of the "Daimon," a spiritual counterpart or guiding spirit that often acts as an opposing force, challenging the individual and shaping their fate. The Daimon calls the artist to a specific, difficult path, pushing them towards their ultimate, often paradoxical, destiny. Yeats reflects on his own artistic journey, the inspirations and the spiritual conflicts that have shaped his work.

Characters	Characteristics	Motivations
W.B. Yeats	Poet, mystic, philosopher, seeker of truth and inspiration. Deeply introspective and spiritual.	To understand the nature of self, creativity, and the spiritual world; to achieve poetic genius and personal wholeness.
The Daimon	A spiritual entity, often perceived as an opposing or challenging force; a guiding spirit or destiny-shaper.	To challenge and guide the individual towards their ultimate spiritual and artistic destiny; to reveal the path of the "anti-self."
The Mask / Anti-Self	A deliberate psychological and artistic construct; the opposite of one's natural self.	To achieve wholeness, artistic power, and a deeper, more authentic identity by embracing paradox and challenging one's inherent nature.

Section: Anima Mundi

The second part, meaning "The Soul of the World," expands beyond the individual soul to explore the collective spiritual realm. Yeats discusses the "Anima Mundi," which he describes as a vast, collective memory or repository of images and experiences accessible to human consciousness. This World Soul contains all historical events, mythical figures, and archetypal images, acting as a source of inspiration and communication for poets and mystics. He recounts various mystical experiences, visions, and encounters with spirits, often achieved through trance states or automatic writing (a practice he shared with his wife, Georgie Hyde-Lees). Yeats posits that the living can communicate with the dead, and that these spiritual entities—which he sometimes refers to as "Frustrators" or "Instructors"—play a role in human affairs, influencing history and personal lives. He suggests that all human souls, post-death, contribute to and draw from this Anima Mundi, shaping the cyclical patterns of human history and creativity. This section lays groundwork for his later, more elaborate philosophical system, A Vision.

Author Facts:

• He was a central figure in the Irish Literary Revival and a co-founder of the Abbey Theatre.
• Yeats was awarded the Nobel Prize in Literature in 1923 "for his always inspired poetry, which in a highly artistic form gives expression to the spirit of a whole nation."

Morale of the Book:
The primary "morale" or insight of Per Amica Silentia Lunae is that true self-knowledge and artistic greatness often require one to look beyond the superficial self, embracing paradox and conflict. It suggests that individuality is not a fixed entity but a dynamic process involving the creation of an "anti-self" and engagement with a spiritual counterpart, the "Daimon." Furthermore, it posits that human consciousness is deeply connected to a collective spiritual reservoir (the Anima Mundi), implying that profound truth and inspiration come from accessing these deeper, often hidden, realms of existence. The book ultimately champions the introspective journey and the willingness to explore the esoteric as paths to creative power and understanding.

Curiosities:

• Precursor to A Vision: Many of the ideas explored in Per Amica Silentia Lunae, particularly the concepts of the Mask, the Daimon, and cyclical history, were later developed into Yeats's elaborate and complex occult system, A Vision.
• Personal Crisis and Spiritual Experimentation: Yeats wrote this book during a period of intense personal and artistic crisis, shortly before his marriage to Georgie Hyde-Lees. His spiritual explorations, including automatic writing sessions with his wife, profoundly shaped the content of the book.
• The Title: The Latin title, "Through the Friendly Silences of the Moon," suggests a journey into solitude, the subconscious, and the nocturnal, intuitive aspects of the mind. The moon is a recurring symbol in Yeats's work, representing cyclical change, mystery, and feminine power.
• Occult Influences: The book is heavily influenced by Yeats's membership in the Hermetic Order of the Golden Dawn, a secret society dedicated to the study of magic, alchemy, and esoteric philosophy, as well as his studies of Neoplatonism and Swedenborg.
