Reality Definition and 435 Threads

Reality is the sum or aggregate of all that is real or existent within a system, as opposed to that which is only imaginary. The term is also used to refer to the ontological status of things, indicating their existence. In physical terms, reality is the totality of a system, known and unknown. Philosophical questions about the nature of reality or existence or being are considered under the rubric of ontology, which is a major branch of metaphysics in the Western philosophical tradition. Ontological questions also feature in diverse branches of philosophy, including the philosophy of science, philosophy of religion, philosophy of mathematics, and philosophical logic. These include questions about whether only physical objects are real (i.e., Physicalism), whether reality is fundamentally immaterial (e.g., Idealism), whether hypothetical unobservable entities posited by scientific theories exist, whether God exists, whether numbers and other abstract objects exist, and whether possible worlds exist.

    Where does reality end and imagination begin?

    Its has occurred to me for some time that there is a fine line between imagination and reality...i think the mistake people always make is with the need to classify an experience as either being an hallucination/aborition or something wholey real. Surely what we percieve as reality (whether...

    Proof of Reality: Electrical Impulses and The Matrix

    Fireplaces and Reality: Understanding the Wave Function

    I have a Laymans understanding of this subject but here goes... I'm sitting now in my living room looking at the fireplace. My act of observation (photons bouncing of the electrons into my eyes) cause the wave function to collapse and create the reality of the fireplace. I now turn my back...

    Experiment and Theory vs. Reality

    I disagree. Experimental agreement is not grounds for establishing a theory. There needs to be a reason, based on some principle, that can explain why these things are true. For example, if I am in a spaceship traveling the speed of light relativity says that I can not walk from one end of...

    Philosophical Thoughts On Our Perceptions of Reality

    Someone posted the following at alt.atheism: How do you know what happens after death? Have you been in that position? If we are the rational skeptics we ought to be, we will doubt that our perception of 'fleshiness', or materialism in general, is a complete and perfect perception. If we...

    Is our personal reality separate from the Mass Reality

    riddle me this! Simply asked, is our personal reality unique and separate from the mass reality while participating in mass events? As an extension, are there an infinite number of realities co-existing simultaneously and creating the observable mass reality?

    Reality vs Sense: Ideas on What Makes Something Real

    Would anyone like to share ideas on what makes something real other than what our senses tell us to believe?

    Is Zero a standard or a reality?

    Another post has been discussing standards used in measuring an observable. We attach a number as a value to use to create other numbers. So I thought I would open a discussion on the standard or reality of Zero. If Zero is a standard but not a reality it would have to be the most...

    From Sand Comes All Things: Challenging the Reality of Creation

    On the existence of Objective reality

    This discussion originally arose in the thread "The answer to the 'Does God exist' question from Human Practice." I'm posting it in a new thread because by now it's a pretty deep tangent to the original thread and it's also an issue worth discussing in its own right. I am not arguing for...

    In terms of mathmatical logical philosophy does reality have to exist?

    Is Paradox the Key to Understanding the Ultimate Reality?

    What is the paradox of the ultimate reality?

    The ultimate reality will be pure paradox. Since if the ultimate conclusion of reality is conclusively logical, we would eventually become bored out of our minds and then we would eventually conclude that our conclusion was irrational seeing that the world no longer makes sense. The "forces"...

    The Heart of Reality: The Mysteries of Life

    What is life, if not that which is held internally? What is essence, if not that which is contained within form?

    Is Reality Merely a Projection of a Singular Mind?
