Per Amica Silentia Lunae — Background and Themes

Dialogue as Structure

The first section, Ego Dominus Tuus, is a verse dialogue between Hic and Ille—two voices that argue about artistic identity. Hic wants to “find myself and not an image,” while Ille claims he must “call to my own opposite.” The debate is not abstract; it is set on “grey sand beside the shallow stream” under a tower where a lamp burns above an open book left by Michael Robartes. This concrete scene gives the philosophical exchange a physical location. The dialogue form itself enacts the central tension: the self is discovered through opposition, not introspection. Yeats uses the voices to stage a conflict between modern self-consciousness and the older, bolder making of images, citing Dante as a figure who “fashioned from his opposite” a stony face.

Recurring Images of Growth and Water

Throughout the essays, Yeats returns to images of plants, water, and gardens to describe the life of images in the Anima Mundi. He speaks of a “great pool or garden” where images spread “like a great water plant” or branch “more fragrantly in the air.” He quotes Spenser’s Garden of Adonis: “There is the first seminary / Of all things that are born to live and die / According to their kynds.” These organic metaphors give the soul’s vehicle a tangible, almost botanical quality. Yeats also describes thoughts as “parasitic vegetables” that start growing beyond our knowledge, coiling out of sight. The image of a seed set growing recurs, linking the generation of ideas to natural processes that unfold without the soul’s direct awareness.

The Vehicle and the General Soul

Yeats draws on Henry More’s definition of the “general soul” as “a substance incorporeal but without sense and animadversion pervading the whole matter of the universe.” He insists, however, that perception and direction belong to the individual soul, and that images exist in a “general vehicle” of Anima Mundi mirrored in our particular vehicle. This distinction allows him to argue that thoughts have “body and period” and can complete themselves out of sight. He gives examples: a wish to wake at seven o’clock that fulfills itself without further thought, or a lady in Balzac who, after a life of sanctity, plans on her deathbed to fly with a renounced lover. These illustrations ground the metaphysical claim in recognizable human experience.

Movement Between Scenes and Authorities

Yeats moves fluidly between personal anecdote, literary reference, and philosophical citation. The prologue’s cat and bramble-bush give way to Dante, Shelley, Blake, and Henry More. He quotes Shelley’s opinion that thoughts called “real or external objects” differ only in regularity from hallucinations and dreams, and notes that Shelley dreamed “three several times between intervals of two or more years the same precise dream.” This shift from the intimate to the learned is characteristic: Yeats treats philosophical authorities as interlocutors in an ongoing conversation. The structure itself mirrors the associative logic he describes—images and ideas draw one another, forming sequences that grow “according to the sundry predispositions and occasions.”

Readers will find that the essays reward attention to their small, specific details: the cat, the bramble-bush, the lamp in the tower, the “pillars of crystal” from Henry More. Yeats builds his argument not by linear proof but by accumulation of images and examples. The work is best approached as a series of meditations that circle the same questions from different angles, each time grounding abstract speculation in a concrete figure. Let the cat’s resolute attention to the bramble-bush be your guide.

Reading again how Yeats let a thought rise from a quiet image—that bramble-bush, that garden—I found myself remembering afternoons with The collected works of William Hazlitt, Vol. 05 (of 12) — Themes and Context open on the windowsill. Both men trusted the unruled mind, letting it wander where it wished. Hazlitt’s moods feel like old friends—familiar, unforced, and oddly consoling in their honesty.
