A classicist, philosopher, and poet, Poul Martin Moller was an important figure in the Danish Golden Age. The traumatic event of the death of his wife led him to think more profoundly about the question of the immortality of the soul. In 1837 he published his most important philosophical treatise, "Thoughts on the Possibility of Proofs of Human Immortality," presented here in English for the first time. It was read and commented upon by the leading figures of the Golden Age, such as Soren Kierkegaard. It proved to be the last important work that Moller wrote before his death in March of 1838 at the age of 43.

The Danish theologian-philosopher K. E. Logstrup is second in reputation in his homeland only to Soren Kierkegaard. He is best known outside Europe for his The Ethical Demand, first published in Danish in 1956 and published in an expanded English translation in 1997. Beyond the Ethical Demand contains excerpts, translated into English for the first time, from the numerous books and essays Logstrup continued to write throughout his life. In the first essay, he engages the critical response to The Ethical Demand, clarifying, elaborating, or defending his original positions. In the next three essays, he extends his contention that human ethics "demands" that we are concerned for the other by introducing the crucial concept of "sovereign expressions of life." Like Levinas, Logstrup saw in the phenomenon of "the other" the ground for his ethics. In his later works he developed this concept of "the sovereign expressions of life," spontaneous phenomena such as trust, mercy, and sincerity that are inherently other-regarding. The last two essays connect his ethics with political life. Interest in Logstrup in the English-speaking academic community continues to grow, and these important original sources will be essential tools for scholars exploring the further implications of his ethics and phenomenology.

Although Pseudo-Dionysius was, after Aristotle, the author whom Thomas Aquinas quoted most frequently, surprisingly little attention has been paid to the role of this Neoplatonist thinker in the formation of Aquinas' philosophy. Fran O'Rourke's book is the only available work that investigates the pervasive influence of Pseudo-Dionysius on Aquinas, while at the same time examining the latter's profound originality. Central themes discussed by O'Rourke include knowledge of the absolute, existence as the first and most universal perfection, the diffusion of creation, the hierarchy of creatures, and their return to God as final end. O'Rourke devotes special attention to the Neoplatonist element in Aquinas' notion of "being" as intensity or degree of perfection. He also considers the relation of being and goodness in light of Aquinas' nuanced reversal of Dionysius' theory of the primacy of the good, and Aquinas' arguments for the transcendental nature of goodness.

Logics of Worlds stands as one of the most important texts in contemporary thought. Conceived as the sequel to Alan Badiou's Being and Event, the book expands upon and elucidates the questions that were posed in the first book. As a complex theory of worlds, the text has, for the most part, been misunderstood, but in William Watkin's diligent and critical close reading of the book, he makes the case for Logics of Worlds being the essential Badiou book for anyone interested in existence, meaning and the potential for radical change. For Watkin, this recasting of ontology is followed by a transformation of logic, which is not only a theory of being, but of appearing and allows Badiou to give new meaning to the object, body and relation. To do this, he explores these concepts through architecture, astronomy and renowned thinkers such as Kant, Hegel and Kierkegaard. For students of French Continental philosophy, ontology and Badiou himself, Watkin's commentary on the philosopher's text provides a brilliant and incisive new interpretation of this underrated work by the leading Continental philosopher of our time.

This study examines the motivations and doctrinal coherence of the Commentary on the Elements of Theology of Proclus written by Berthold of Moosburg, O.P. ( c. 1361/1363). It provides an overview of Berthold's biography and intellectual contexts, his manuscript remains, and a partial edition of his annotations on Macrobius and Proclus. Through a close analysis of the three prefaces to the Commentary, giving special attention to Berthold's sources, it traces the Dominican's elaboration of Platonism as a soteriological science. The content of this science is then presented in a systematic reconstruction of Berthold's cosmology and anthropology. The volume includes an English translation of the three fundamental prefaces of the Commentary. The publication of this volume has received the generous support of the European Research Council (ERC) under the European Union's Horizon 2020 research and innovation programme through the ERC Consolidator Grant NeoplAT: A Comparative Analysis of the Middle East, Byzantium and the Latin West (9th-16th Centuries), grant agreement No 771640 (www.neoplat.eu).

Horst Ruthrof revisits Husserl's phenomenology of language and highlights his late writings as essential to understanding the full range of his ideas. Focusing on the idea of language as imaginable as well as the role of a speech community in constituting it, Ruthrof provides a powerful re-assessment of his methodological phenomenology. From the Logical Investigations to untranslated portions of his Nachlass, Ruthrof charts all the developments and amendments in his theorizations. Ruthrof argues that it is the intersubjective character to linguistic meaning that is so emblematic of Husserl's position. Bringing his study up to the present day, Ruthrof discusses mental time travel, the evolution of language, and protosyntax in the context of Husserl's late writings, progressing a comprehensive new phenomenological ontology of language with wide-ranging implications for philosophy, linguistics, and cultural studies.

The philosopher Abu Nasr al-Farabi (c. 870-c. 950 CE) is a key Arabic intermediary figure. He knew Aristotle, and in particular Aristotle's logic, through Greek Neoplatonist interpretations translated into Arabic via Syriac and possibly Persian. For example, he revised a general description of Aristotle's logic by the 6th century Paul the Persian, and further influenced famous later philosophers and theologians writing in Arabic in the 11th to 12th centuries: Avicenna, Al-Ghazali, Avempace and Averroes. Averroes' reports on Farabi were subsequently transmitted to the West in Latin translation. This book is an abridgement of Aristotle's Prior Analytics, rather than a commentary on successive passages. In it Farabi discusses Aristotle's invention, the syllogism, and aims to codify the deductively valid arguments in all disciplines. He describes Aristotle's categorical syllogisms in detail; these are syllogisms with premises such as 'Every A is a B' and 'No A is a B'. He adds a discussion of how categorical syllogisms can codify arguments by induction from known examples or by analogy, and also some kinds of theological argument from perceived facts to conclusions lying beyond perception. He also describes post-Aristotelian hypothetical syllogisms, which draw conclusions from premises such as 'If P then Q' and 'Either P or Q'. His treatment of categorical syllogisms is one of the first to recognise logically productive pairs of premises by using 'conditions of productivity', a device that had appeared in the Greek Philoponus in 6th century Alexandria.

The Holy Science is a book of theology written by Swami Sri Yukteswar Giri in 1894. The text provides a close comparison of parts of the Christian Bible to the Hindu Upanishads, meant "to show as clearly as possible that there is an essential unity in all religions...and that there is but one Goal admitted by all scriptures."

Swami Sri Yukteswar Giri was born Priya Nath Karar in 1855 to a wealthy family. As a young man, he was a brilliant student of math and science, astrology and astronomy. He joined a Christian missionary school where he studied the Bible and later spent two years in medical school.

After completing his formal education, Priya Nath married and had a daughter. But he continued his intellectual and spiritual pursuits, depending on the income from his property to support himself and his family.

After the death of his wife, he entered the monastic Swami order and became Sri Yuktesvar Giri, before becoming a disciple of famed guru Lahiri Mahasaya, known for his revitalization of Kriya Yoga. Then in 1894, Sri Yuktesvar Giri met Mahavatar Babaji, an ageless wise man who is said to have lived for untold hundreds of years. At this meeting, Mahavatar Babaji gave Sri Yuktesvar the title of Swami, and asked him to write this book comparing Hindu scriptures and the Christian Bible. Swami Sri Yuktesvar obeyed.

He also founded two ashrams, including one in his ancestral home. He lived simply as a swami and yogi, devoted to disciplining his body and mind, and thus to liberating his soul. Among his disciples was Paramahansa Yogananda, credited with bringing yoga and meditation to millions of Westerners.

The Holy Science consists of four chapters. The first is titled "The Gospel," and is intended to "establish the fundamental truth of creation." Next is "The Goal," which discusses the three things all creatures are seeking: "Existence, Consciousness, and Bliss."

Chapter three, "The Procedure," is the most practical of the sections. It describes the natural way to live for purity and health of body and mind. The final chapter is called "The Revelation," and discusses the end of the path for those who are near the "three ideals of life."

Swami Sri Yukteswar also displays his impressive knowledge and understanding of astrology by proposing his theory of the Yuga Cycle.

Each yuga is an age of the world that tracks the movement of the sun, Earth, and planets. Each age represents a different state of humanity. There are four yugas:

- Satya Yuga is the highest and most enlightened age of truth and perfection.

- Treta Yuga is the age of thought and is more spiritually advanced than Dwapara Yuga and Kali Yuga.

- Dwapara Yuga is an energetic age, although not a wise one. During this yuga, people are often self-serving and greedy. The age is marked by war and disease.

- Kali Yuga is the age of darkness, ignorance, and materialism. This is the least evolved age.

Today, The Holy Science is highly respected among those seeking to understand the relationships between world religions and cultures. While some still believe that we are in Kali Yuga, many others believe that Swami Sri Yukteswar was accurate, and that his calculations correct previous errors that artificially inflated the length of the Yuga Cycle.
