Discusses the general nature of philosophy and its values, logic, mathematics, physics, a general approach to ontology, epistemology (the nature - and limits - of human knowledge), an outlook on cosmology, human and animal psychology, human ethics, and the divine reality.

We barely talk about them and seldom know their names. Philosophy has always overlooked them; even biology considers them as mere decoration on the tree of life. And yet plants give life to the Earth: they produce the atmosphere that surrounds us, they are the origin of the oxygen that animates us. Plants embody the most direct, elementary connection that life can establish with the world. In this highly original book, Emanuele Coccia argues that, as the very creator of atmosphere, plants occupy the fundamental position from which we should analyze all elements of life. From this standpoint, we can no longer perceive the world as a simple collection of objects or as a universal space containing all things, but as the site of a veritable metaphysical mixture. Since our atmosphere is rendered possible through plants alone, life only perpetuates itself through the very circle of consumption undertaken by plants. In other words, life exists only insofar as it consumes other life, removing any moral or ethical considerations from the equation. In contrast to trends of thought that discuss nature and the cosmos in general terms, Coccia’s account brings the infinitely small together with the infinitely big, offering a radical redefinition of the place of humanity within the realm of life.

The idea that some parts of reality are fundamental and others derivative was an important one in Aristotle's philosophical system, and is now again of great current interest in philosophy. Michail Peramatzis presents a new account of priority relations in Aristotle's metaphysics, and draws out their continuing philosophical significance.

Nietzsche is famous for rejecting a great many standard philosophical methods. He does this on the basis of critical assessments of these methods. Nietzsche's historical critiques are justly famous but the question of what his new philosophy is often not explored. The important issue is what Nietzsche believed were some of the possibilities left for philosophy if his criticisms of previous philosophies were correct. This book is called the 'Reclamation of Philosophy' because Nietzsche is engaged in a task of reappropriating certain characteristics of past philosophies into his work. He reclaims philosophical reflection as practiced by French moralists, some Presocratic philosophers, and some German thinkers. As a mature writer he is no longer interested in philosophy simply as a place to display skill in analytic or logical reasoning. He is interested in a philosophy which can address the cultural and personal issues of people constructing themselves in their world. He is particularly interested in using philosophical talents to help to discover the values implicit in practices and assumptions which people hold. These 'values' are not just moral and aesthetic they are also epistemologically relevant. Nietzsche's Reclamation of Philosophy elucidates what Nietzsche has to say about value; particularly what he has to say about moral value, by looking at his views of aesthetic value.

Jean Grondin completes the first history of metaphysics and respects both the analytical and the Continental schools while transcending the theoretical limitations of each. He reviews seminal texts by Parmenides, Plato, Aristotle, Plotinus, and Augustine. He follows the theological turn in the metaphysical thought of Avicenna, Anselm, Aquinas, and Duns Scotus, and he revisits Descartes and the cogito; Spinoza and Leibniz's rationalist approaches; Kant's reclaiming of the metaphysical tradition; and post-Kantian practice up to Hegel. He engages with twentieth century innovations that upended the discipline, particularly Heidegger's revival of the question of Being and the rediscovery of the metaphysics of existence by Sartre and the Existentialists, language by Gadamer and Derrida, and transcendence by Levinas. Metaphysics is often dismissed as a form or epoch of philosophy that must be overcome, yet by promoting a full understanding of its platform and processes, Grondin reveals its cogent approach to reality and foundational influence on modern philosophy and science. By restoring the value of metaphysics for contemporary audiences, Grondin showcases the rich currents and countercurrents of metaphysical thought and its future possibilities.

Some of the world's specialists provide in this handbook essays about what kinds of things there are, in what ways they exist, and how they relate to each other. They give the word on such topics as identity, modality, time, causation, persons and minds, freedom, and vagueness.

In Guerrilla Metaphysics, Graham Harman develops further the object-oriented philosophy first proposed in Tool-Being. Today’s fashionable philosophies often treat metaphysics as a petrified relic of the past, and hold that future progress requires an ever further abandonment of all claims to discuss reality in itself. Guerrilla Metaphysics makes the opposite assertion, challenging the dominant "philosophy of access" (both continental and analytic) that remains quarantined in discussions of language, perception, or literary texts. Philosophy needs a fresh resurgence of the things themselves—not merely the words or appearances themselves. Once these themes are adapted to the needs of an object-oriented philosophy, what emerges is a brand new type of metaphysics—a "guerrilla metaphysics."
