In Above Time, James R. Guthrie explores the origins of the two preeminent transcendentalists' revolutionary approaches to time, as well as to the related concepts of history, memory, and change. Most critical discussions of this period neglect the important truth that the entire American transcendentalist project involved a transcendence of temporality as well as of materiality. Correspondingly, both writers call in their major works for temporal reform, to be achieved primarily by rejecting the past and future in order to live in an amplified present moment.

Emerson and Thoreau were compelled to see time in a new light by concurrent developments in the sciences and the professions. Geologists were just then hotly debating the age of the earth, while zoologists were beginning to unravel the mysteries of speciation, and archaeologists were deciphering the Egyptian hieroglyphs. These discoveries worked collectively to enlarge the scope of time, thereby helping pave the way for the appearance of Darwin's Origin of Species in 1859.

Well aware of these wider cultural developments, Emerson and Thoreau both tried (although with varying degrees of success) to integrate contemporary scientific thought with their preexisting late-romantic idealism. As transcendentalists, they already believed in the existence of "correspondences"—affinities between man and nature, formalized as symbols. These symbols could then be decoded to discover the animating presence in the world of eternal laws as pervasive as the laws of science. Yet unlike scientists, Emerson and Thoreau hoped to go beyond merely understanding nature to achieving a kind of passionate identity with it, and they believed that such a union might be achieved only if time was first recognized as being a purely human construct with little or no validity in the rest of the natural world. Consequently, both authors employ a series of philosophical, rhetorical, and psychological strategies designed to jolt their readers out of time, often by attacking received cultural notions about temporality.

Born into a family of attorneys, Dickinson absorbed law at home. She employed legal terms and concepts regularly in her writings, and her metaphors grounded in law derive much of their expressive power from a comparatively sophisticated lay knowledge of the various legal and political issues that were roiling nineteenth-century America. Dickinson displays interest in such areas as criminal law, contracts, equity, property, estate law, and bankruptcy. She also held in high regard the role of law in resolving disputes and maintaining civic order. Toward the end of her life, Dickinson cited the Spartans' defense at Thermopylae as an object lesson demonstrating why societies should uphold the rule of law.

Yet Dickinson was also capable of criticizing, even satirizing, law and lawyers. Her poetic personae inhabit various legal roles including those of jurymen, judges, and attorneys, and some poems simulate courtroom contests pitting the rights of individuals against the power of the state. She was keenly interested in legal matters pertaining to women, such as breach of promise, dower, and trusts. With her tone ranging from subservient to domineering, from reverential to ridiculing, Dickinson's writings reflect an abiding concern with philosophic and political principles underpinning the law, as well as an identification with the plight of individuals who dared confront authority.

A Kiss from Thermopylae reveals a new dimension of Dickinson's writing and thinking, one indicating that she was thoroughly familiar with the legal community's idiomatic language, actively engaged with contemporary political and ethical questions, and skilled at deploying a poetic register ranging from high romanticism to low humor.
