Existence is the state of having being or reality in contrast to nonexistence and nonbeing. Existence is often contrasted with essence: the essence of an entity is its essential features or qualities, which can be understood even if one does not know whether the entity exists.
Georg Wilhelm Friedrich Hegel was a German philosopher and one of the most influential figures of German idealism and 19th-century philosophy. His influence extends across the entire range of contemporary philosophical topics, from metaphysical issues in epistemology and ontology, to political philosophy, the philosophy of history, philosophy of art, philosophy of religion, and the history of philosophy.
Immanuel Kant was a German philosopher and one of the central Enlightenment thinkers. Born in Königsberg, Kant's comprehensive and systematic works in epistemology, metaphysics, ethics, and aesthetics have made him one of the most influential and controversial figures in modern Western philosophy. He has been called the "father of modern ethics", the "father of modern aesthetics", and for bringing together rationalism and empiricism, the "father of modern philosophy".
Metaphysics is the branch of philosophy that examines the basic structure of reality. It is traditionally seen as the study of mind-independent features of the world, but some theorists view it as an inquiry into the conceptual framework of human understanding. Some philosophers, including Aristotle, designate metaphysics as first philosophy to suggest that it is more fundamental than other forms of philosophical inquiry.
Dialectic, also known as the dialectical method, refers originally to dialogue between people holding different points of view about a subject but wishing to arrive at the truth through reasoned argumentation. Dialectic resembles debate, but the concept excludes subjective elements such as emotional appeal and rhetoric. It has its origins in ancient philosophy and continued to be developed in the Middle Ages.
Objective idealism is a philosophical theory that affirms the ideal and spiritual nature of the world and conceives of the idea of which the world is made as the objective and rational form in reality rather than as subjective content of the mind or mental representation. Objective idealism thus differs both from materialism, which holds that the external world is independent of cognizing minds and that mental processes and ideas are by-products of physical events, and from subjective idealism, which conceives of reality as totally dependent on the consciousness of the subject and therefore relative to the subject itself.
In philosophy and the arts, a fundamental distinction is between things that are abstract and things that are concrete. While there is no general consensus as to how to precisely define the two, examples include that things like numbers, sets, and ideas are abstract objects, while plants, dogs, and planets are concrete objects. Popular suggestions for a definition include that the distinction between concreteness versus abstractness is, respectively: between (1) existence inside versus outside space-time; (2) having causes and effects versus not; 3) being related, in metaphysics, to particulars versus universals; and (4) belonging to either the physical versus the mental realm. Another view is that it is the distinction between contingent existence versus necessary existence; however, philosophers differ on which type of existence here defines abstractness, as opposed to concreteness. Despite this diversity of views, there is broad agreement concerning most objects as to whether they are abstract or concrete, such that most interpretations agree, for example, that rocks are concrete objects while numbers are abstract objects.
In Greek mythology, a little owl traditionally represents or accompanies Athena, the virgin goddess of wisdom, or Minerva, her syncretic incarnation in Roman mythology. Because of such association, the bird—often referred to as the "owl of Athena" or the "owl of Minerva"—has been used as a symbol of knowledge, wisdom, perspicacity and erudition throughout the Western world.

Dialectical materialism is a materialist theory based upon the writings of Karl Marx and Friedrich Engels that has found widespread applications in a variety of philosophical disciplines ranging from philosophy of history to philosophy of science. As a materialist philosophy, Marxist dialectics emphasizes the importance of real-world conditions and the presence of functional contradictions within and among social relations, which derive from, but are not limited to, the contradictions that occur in social class, labour economics, and socioeconomic interactions. Within Marxism, a contradiction is a relationship in which two forces oppose each other, leading to mutual development.
