What is Metaphysics: Definition and 28 Discussions

Metaphysics is the branch of philosophy that examines the fundamental nature of reality, including the relationship between mind and matter, between substance and attribute, and between potentiality and actuality. The word "metaphysics" comes from two Greek words that, together, literally mean "after or behind or among [the study of] the natural". It has been suggested that the term might have been coined by a first century CE editor who assembled various small selections of Aristotle’s works into the treatise we now know by the name Metaphysics (μετὰ τὰ φυσικά, meta ta physika, lit. 'after the Physics ', another of Aristotle's works).Metaphysics studies questions related to what it is for something to exist and what types of existence there are. Metaphysics seeks to answer, in an abstract and fully general manner, the questions:
What is there?
What is it like?Topics of metaphysical investigation include existence, objects and their properties, space and time, cause and effect, and possibility. Metaphysics is considered one of the four main branches of philosophy, along with epistemology, logic, and ethics.

    I How Does Quantum Measurement Influence Reality Splitting in Many Worlds Theory?

    In many words a split occurs when a quantum measurement occurs, this split would then 'radiate' out into the universe. So say a quantum measurement of an electron happens on the moon. The information from the measurement would travel to let's say some people. These people would then unknowingly...

    Is logical positivism really dead? Where art metaphysics?
