When our smartphones distract us, much more is at stake than a momentary lapse of attention. Our use of smartphones can interfere with the building-blocks of meaningfulness and the actions that shape our self-identity. By analyzing social interactions and evolving experiences, Roholt reveals the mechanisms of smartphone-distraction that impact our meaningful projects and activities. Roholt's conception of meaning in life draws from a disparate group of philosophers - Susan Wolf, John Dewey, Hubert Dreyfus, Martin Heidegger, and Albert Borgmann. Central to Roholt's argument are what Borgmann calls focal practices: dinners with friends, running, a college seminar, attending sporting events. As a recurring example, Roholt develops the classification of musical instruments as focal things, contending that musical performance can be fruitfully understood as a focal practice. Through this exploration of what generates meaning in life, Roholt makes us rethink the place we allow smartphones to occupy in the everyday. But he remains cautiously optimistic. This thoughtful, needed interrogation of smartphones shows how we can establish a positive role for technologies within our lives.

When we talk about delusions we may refer to symptoms of mental health problems, such as clinical delusions in schizophrenia, or simply the beliefs that people cling to which are implausible and resistant to counterevidence; these can include anything from beliefs about the benefits of homeopathy to concerns about the threat of alien abduction. Why do people adopt delusional beliefs and why are they so reluctant to part with them? In Why Delusions Matter, Lisa Bortolotti explains what delusions really are and argues that, despite their negative reputation, they can also play a positive role in people's lives, imposing some meaning on adverse experiences and strengthening personal or social identities. In a clear and accessible style, Bortolotti contributes to the growing research on the philosophy of the cognitive sciences, offering a novel and nuanced view of delusions.

Connecting several strands of Aristotle's thought, Zoli Filotas sheds light on one of the axioms of Aristotle's ethics and political philosophy - that every community has a ruler - and demonstrates its relevance to his ideas on personal relationships. Aristotle and the Ethics of Difference, Friendship, and Equality reveals a pluralistic theory of rule in Aristotle's thought, tracing it through his corpus and situating it in a discussion among such figures as Gorgias, Xenophon, and Plato. Considering the similarities and differences among various forms of rule, Filotas shows that for Aristotle even virtuous friends must exercise a version of rule akin to that of slaveholders. He also explores why Aristotle distinguishes the hierarchical rule over women from both the mastery of slaves and the political rule exercised by free and equal citizens. In doing so, he argues that natural and social differences among human beings play a complex, and troubling, role in Aristotle's reasoning. Illuminating and thought-provoking, this book reveals Aristotle's ambivalence about political relations and the equal treatment they involve and offers an engaging inquiry into how he understood the common structures of human relationships.

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.

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.

The fundamental burden of a theory of inductive inference is to determine which are the good inductive inferences or relations of inductive support and why it is that they are so. The traditional approach is modeled on that taken in accounts of deductive inference. It seeks universally applicable schemas or rules or a single formal device, such as the probability calculus. After millennia of halting efforts, none of these approaches has been unequivocally successful and debates between approaches persist.The Material Theory of Induction identifies the source of these enduring problems in the assumption taken at the outset: that inductive inference can be accommodated by a single formal account with universal applicability. Instead, it argues that that there is no single, universally applicable formal account. Rather, each domain has an inductive logic native to it. Which that is, and its extent, is determined by the facts prevailing in that domain. Paying close attention to how inductive inference is conducted in science and copiously illustrated with real-world examples, The Material Theory of Induction will initiate a new tradition in the analysis of inductive inference.

At the intersection between psychoanalysis (Freudian and Lacanian) and philosophy, this book is a glimpse into the life of patients, into desire and love, and into the fate of the relationship between men and women.

In his Treatise on the Virtues, Aquinas discusses the character and function of habit; the essence, subject, cause, and meaning of virtue; and the separate intellectual, moral, cardinal, and theological virtues. His work constitutes one of the most thorough and incisive accounts of virtue in the history of Christian philosophy. John Oesterle's accurate and elegant translation makes this enduring work readily accessible to the modern reader.

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.

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.
