This is a translation of an early essay by the German philosopher Nicolai Hartmann (1882–1950). In this 1923 essay Hartmann presents many of the fundamental ideas of his new critical ontology. He summarizes some of the main points of his critique of neo-Kantian epistemology, and provides the point of departure for his new approach in an extensive criticism of the errors of the classical ontological tradition. Some of these errors concern the definition of an ontological category or principle, and others concern the relations among categories themselves. The outline for the new ontology is sketched through the correctives Hartmann appends to the treatment of each error, prefiguring his mature ontological system

People tend to enjoy listening to music or watching television, sleeping at night and celebrating birthdays. Plants tend to grow and thrive in sunlight and mild temperatures. We also know that tendencies are not perfectly regular and that there are patterns in the natural world, which are reliable to a degree, but not absolute. What should we make of a world where things tend to be one way but could be another? Is there a position between necessity and possibility? If there is, what are the implications for science, knowledge and ethics? This book explores these questions and is the first full-length treatment of the philosophy of tendencies. Anjum and Mumford argue that although the philosophical language of tendencies has been around since Aristotle, there has not been any serious commitment to the irreducible modality that they involve. They also argue that the acceptance of an irreducible and sui generis tendential modality ought to be the fundamental commitment of any genuine realism about dispositions or powers. It is the dispositional modality that makes dispositions authentically disposition-like. Armed with this theory the authors apply it to a variety of key philosophical topics such as chance, causation, epistemology and free will.

It is still a widespread assumption that metaphysics and ontology deal with roughly the same questions. They are supposed to be concerned with the fundamental nature of reality and to give an account of the meaning of 'existence' or 'being' in line with the broadest possible metaphysical assumptions. Against this, Markus Gabriel proposes a radical form of ontological pluralism that divorces ontology from metaphysics, understood as the most fundamental theory of absolutely everything. He argues that the concept of existence is incompatible with the existence of the world and therefore proposes his innovative no-world-view. In the context of recent debates surrounding new realism and speculative realism, Gabriel also develops the outlines of a realist epistemological pluralism. His idea here is that there are different forms of knowledge that correspond to the plurality of fields of sense that must be acknowledged in order to avoid the trap of metaphysics.
