This study set out to compare and analyze the influences Kabbalah, which was Louis I. Kahn's faith as a Jew, on his architecture based on Freud's psychoanalysis that had many exchanges with modernism and contemporary architecture and the analytical psychology of Jung that affected Kahn in examining his architecture and theories. The specific goals of the study were to shed light to Kahn's presence in contemporary architecture anew and establish the methodology of using psychoanalysis in building new theories of architectural planning. When the theories of psychoanalysis were introduced for comparison and analysis purposes, Kahn tried to differentiate his buildings by placing a function or symbolic central space at the heart of a building even though he did adopt a characteristic of modernism architecture, which was placing a core at the centre of plan, for a while. Such a tendency of his was based on Jung's opinions rather than Freud's and affected by Ecole des Beaux-Art. The analysis results also indicate that he conceived "Served Space & Servant Space," "architecture of connection" and "silence and light" that made up the essence of his architectural theory from the relationships between Ayin-Sof, Kabbalah's absolute god, and Sefiroth. It's also very likely that his often use of triangles and circles in his architecture was affected by the Tree of Sefiroth diagram of Kabbalah. His tendency is well reflected in Salk Institute and Philips Exeter Academy Library, where he placed a laboratory or courtyard at the center where a core was supposed to be, created a corridor or courtyard space between those central spaces and the core, and connected them one another with circulation. Thus he succeeded in embodying the concept of Tree of Sefiroth with which to perceive the being of Ayin-Sof into an architectural space, which is well proven with Mikveh Israel Synagogue where he directly applied the Tree of Sefiroth diagram. The synagogue also contained a hollow column that served as an important concept in his late architecture. The hollow column was also the result of him applying the concept of Sefiroth to the place where Ayin-Sof was reduced in Kabbalah.

Yeats's poetry and writings were a display of his passion for mysticism and the occult. This view on Yeats has been largely expressed in various publications. Many of Yeats's critics, including Ellmann, agree that the roots of Yeats's system are in Theosophy. The roots of Yeats's philosophy are in Theosophy, being a comprehensive, unifying systems of all occult tradition, and the first metaphysical system that Yeats encountered. Being faced with the dilemma between faith and disbelief, Yeats contacted numerous texts on the subject occultism and met Blavatsky, the founder of Theosophy society, claimed to have the ability to offer a "synthesis" of religion, science, and philosophy. After many metaphysical conversations with her and many hours of long thought on the issue, Yeats took one of his first steps on his path of occult wisdom. Yeats's fascination with occultism and mysticism was so profound, and his need to create a unifying mythology so great, that he decided to develop an esoteric system of his own. Thus, between 1917 and 1925, Yeats had written A Vision, an elaborate, complicated system that is of importance in understanding Yeats's works. The first version, published in 1925, was later revised, and final version was published in 1937. In Book IV and V of A Vision Yeats had expounded the notion that history moves in great two-thousand-year cycles. This circle represents the moon and the twenty-eight phases of the moon which are closely related to the progression of time and world history. Yeats suggested all things are subject to a cycle of changes, which can be regarded as bi-polar, passing from a state of objectivity to one of subjectivity before returning to objectivity again. In this view he was strongly influenced by the Theosophists, especially Blavatsky and the Kabbalists, who saw the law of periodicity as one of the fundamental and absolute laws of the universe. Yeats believed that history was cyclic and that every 2,000 years a new cycle begins, which is the opposite of the cycle that has preceded it. In his poem "The Second Coming," the birth of Christ begins one cycle, which ends, as the poem ends, with a "rough beast," mysterious and menacing, who "slouches towards Bethlehem to be born." Yeats's theory of the historical cycle is directly related to his belief in a universal duality -- the existence of opposite but equal forces that dominate a cycle alternately. This view is in accordance with the occult traditions which teach that the First Cause exhibits periodically different aspects of itself. Yeats believed that kingdoms rise movement of history is an hour within the day of a large movement, and that all these cycles are caught within one all-inclusive "Great Year" which has a cosmic purpose. The Kabbalah says the alternation between judgement and mercy must be on equal terms. The germ finally goes back to its root principle, the Unity out of which everything proceeds.
