Identity of indiscerniblesThe identity of indiscernibles is an ontological principle that states that there cannot be separate objects or entities that have all their properties in common. That is, entities x and y are identical if every predicate possessed by x is also possessed by y and vice versa. It states that no two distinct things (such as snowflakes) can be exactly alike, but this is intended as a metaphysical principle rather than one of natural science. A related principle is the indiscernibility of identicals, discussed below.
MonadologyThe Monadology (La Monadologie, 1714) is one of Gottfried Leibniz's best known works of his later philosophy. It is a short text which presents, in some 90 paragraphs, a metaphysics of simple substances, or monads. During his last stay in Vienna from 1712 to September 1714, Leibniz wrote two short texts in French which were meant as concise expositions of his philosophy. After his death, Principes de la nature et de la grâce fondés en raison, which was intended for prince Eugene of Savoy, appeared in French in the Netherlands.
Dasein'Dasein' (ˈdaːzaɪn) (sometimes spelled as Da-sein) is the German word for 'existence'. It is a fundamental concept in the existential philosophy of Martin Heidegger. Heidegger uses the expression Dasein to refer to the experience of being that is particular to human beings. Thus it is a form of being that is aware of and must confront such issues as personhood, mortality and the dilemma or paradox of living in relationship with other humans while being ultimately alone with oneself.
Meta-ontologyMeta-ontology is the study of the field of inquiry known as Ontology. The goal of meta-ontology is to clarify what ontology is about and how to interpret the meaning of ontological claims. Different meta-ontological theories disagree on what the goal of ontology is and whether a given issue or theory lies within the scope of ontology. There is no universal agreement whether meta-ontology is a separate field of inquiry besides ontology or whether it is just one branch of ontology.
Mental substanceLa substance pensante est l'idée soutenue par les tenants du dualisme et de l'idéalisme, que les esprits sont constitués de substance non physique. Cette substance est souvent dénommée conscience. Ce concept s'oppose au matérialisme, qui soutient que ce que nous pensons normalement comme étant une substance mentale n'est finalement que de la matière physique (c'est-à-dire un cerveau). Descartes, célèbre pour son affirmation « Je pense donc je suis », a eu beaucoup d'influence sur le problème corps-esprit.
Divine simplicityIn monotheistic theology, the doctrine of Divine Simplicity says that God is simple (without parts). This is the idea that God does not exist in parts but is one unified entity, with no distinct attributes; that is, God’s existence is identical to God’s essence. The general idea can be stated in this way: The being of God is identical to the "attributes" of God. Characteristics such as omnipresence, goodness, truth, eternity, etc.
Speculative realismSpeculative realism is a movement in contemporary Continental-inspired philosophy (also known as post-Continental philosophy) that defines itself loosely in its stance of metaphysical realism against its interpretation of the dominant forms of post-Kantian philosophy (or what it terms "correlationism"). Speculative realism takes its name from a conference held at Goldsmiths College, University of London in April 2007.
