Idealism is broadly understood as the contention that ultimate reality is immaterial or dependent on mind, so that matter is in some sense derivative, emergent, and at best conditionally real. Idealism flourished in Britain in the last third of the nineteenth century and first two decades of the twentieth. British idealists such as Bernard Bosanquet, T.
If one were to look at a tree one day, and the tree later lost a leaf, it would seem that one could still be looking at that same tree. Two rival theories to account for the relationship between change and identity are perdurantismwhich treats the tree as a series of tree-stages, and endurantismwhich maintains that the organism—the same tree—is present at every stage in its history.
Space and time[ edit ] See also: Philosophy of space and time Objects appear to us in space and time, while abstract entities such as classes, properties, and relations do not. What then is meant by space and time such that it can serve this function as a ground for objects?
Are space and time entities themselves, of some form, or must they exist prior to other entities? How exactly can they be defined? For example, if time is defined as a "rate of change" then must there always be something changing in order for time to exist?
Causality Classical philosophy recognized a number of causes, including teleological future causes.

In special relativity and quantum field theory the notions of space, time and causality become tangled together, with temporal orders of causations becoming dependent on who is observing them.
The laws of physics are symmetrical in time, so could equally well be used to describe time as running backwards.
Why then do we perceive it as flowing in one direction, the arrow of timeand as containing causation flowing in the same direction? Causality is linked by most philosophers to the concept of counterfactuals. To say that A caused B means that if A had not happened then B would not have happened.
Causality is usually required as a foundation for philosophy of scienceif science aims to understand causes and effects and make predictions about them. Necessity and possibility[ edit ] See also: Modal logic and Modal realism Metaphysicians investigate questions about the ways the world could have been.
David Lewisin "On the Plurality of Worlds," endorsed a view called Concrete Modal realismaccording to which facts about how things could have been are made true by other concrete worlds, just as in ours, in which things are different. Other philosophers, such as Gottfried Leibnizhave dealt with the idea of possible worlds as well.
The idea of necessity is that any necessary fact is true across all possible worlds. A possible fact is true in some possible world, even if not in the actual world. For example, it is possible that cats could have had two tails, or that any particular apple could have not existed.
By contrast, certain propositions seem necessarily true, such as analytic propositionse. A less controversial view might be that self-identity is necessary, as it seems fundamentally incoherent to claim that for any x, it is not identical to itself; this is known as the law of identity, a putative "first principle".
Aristotle describes the principle of non-contradiction, "It is impossible that the same quality should both belong and not belong to the same thing This is the most certain of all principles Wherefore they who demonstrate refer to this as an ultimate opinion.
For it is by nature the source of all the other axioms.The first major work in the history of philosophy to bear the title “Metaphysics” was the treatise by Aristotle that we have come to know by that name. An introduction to the five branches of philosophy: Metaphysics, Epistemology, Ethics, Politics, and Esthetics, and how they relate to one another.
Nature of metaphysics. Metaphysics can be described as all of the following: Branch of philosophy – philosophy is the study of general and fundamental problems, such as those connected with existence, knowledge, values, reason, mind, and language.
Philosophy is distinguished from other ways of addressing such problems by its critical, generally systematic approach and its reliance on. In Western philosophy, metaphysics has become the study of the fundamental nature of all reality — what is it, why is it, and how are we can understand ashio-midori.com treat metaphysics as the study of “higher” reality or the “invisible” nature behind everything, but instead, it's the study of all of reality, visible and invisible.
Metaphysics is the branch of philosophy that studies the essence of a thing. This includes questions of being, becoming, existence, and reality. The word "metaphysics" comes from the Greek words that literally mean "beyond nature".
"Nature" in this sense refers to . Metaphysics What is Metaphysics?
Metaphysics is the branch of philosophy responsible for the study of existence. It is the foundation of a worldview.
