“Spirit” in antiquity was seen as the uncontrollable, dynamic, and numinous presence of divine power. It had no relation to rationality, nor were human beings masters of this spirit. On the contrary, it was thoroughly irrational and entirely the agent of the gods. When the spirit was present in human beings, its manifestations were poetry, prophecy, visions, ecstasy, and speaking in tongues.

One of the methodical approaches to the tradition in the Gospel of Thomas is the search for Aramaisms in order to ascertain the Semitic background of the logia of Jesus. Aramaic, admittedly, was the language of Jesus and of the earliest strata of the Gospel tradition. Therefore, the discovery of Aramaisms or at least of a Semitic coloring in the Greek or Coptic wording could be helpful in reconstructing a pre-Greek or presynoptic stage of tradition. Some scholars have claimed to have traced genuine Aramaisms in the logia of the Gospel of Thomas that would carry us back to the earliest stages of oral or written tradition in the Aramaic speaking communities. It has been argued that in several cases Semitic coloring in the sayings of the Gospel of Thomas is stronger than in their synoptic parallels. If this observation is true, it would help in establishing the independence of the Gospel of Thomas. In itself this methodological approach is legitimate and should be applied to each of the logia preserved in this document. It is important, however, to avoid generalizations. If real Aramaisms are found in a logion, this may point to the archaic character of that specific logion, but this is not proof that the whole document is therefore rooted in early Aramaic tradition.

The Periphyseon, the magnum opus of the Carolingian thinker Johannes Scottus Eriugena (810–877), is widely recognized as the most original work in the history of Christian thought between Augustine and Anselm. Set in the form of a dialogue between a Master and his Student, the Periphyseon presents a daring view of the universe, for which Eriugena coins the term natura. Instead of the traditional Christian dichotomy of God versus creation, Eriugena presents a unified view of reality, the intimidating whole of which he can only conceive by submitting it to a process of division. Hence the name Periphyseon or On the Division of Nature.

The year 1991 marked the sesquicentennial of the publication of the first volume of Emerson's Essays in which appeared, for the first time, “Self-Reliance,” arguably America's most famous essay. Despite the passage of time, this essay has never lost its power to inspire or to enrage. The controversies that continue to swirl around Emerson originate in a few points of contention, but none arouse as much furor as his seemingly innocuous formulation “self-reliance.” From the beginning, Emerson's reception among his readers has been sharply divided. A sampling of studies appearing in the current flood of Emerson criticism suggests that this polarization has never been more characteristic of Emerson's readership than it is currently. On the one hand are those critics of American culture like the late A. Bartlett Giamatti who found Emerson “as sweet as barbed wire” or the sociologist of religion Robert Bellah who located in Emerson the roots of America's most portentous national defects. On the other hand are such notable critics as Harold Bloom, Stanley Cavell, and Richard Poirier who find in Emerson, rightly read and construed, one of the few viable trails left in contemporary culture. The crux of all such articulate responses, whether of detractor or partisan, is the reflexive and seemingly disinterested conception popularized by Emerson as “self-reliance.”

Blake's romantic genius could not but chafe at the theme of rational order and harmony that pervaded eighteenth-century science, art, and theology. Only spiritual blindness could be content with a world reducible to measure and mathematics. Blake longed for a grander synthesis—a celebration of human living beyond the antinomies of reason and passion, understanding and imagination, order and chaos. He longed for the marriage of heaven and hell.
