Topic: The existence of physical objects


  
  Existence - Wikipedia, the free encyclopedia
The word "existence", on this view, is simply a way of describing the logical form of ordinary subject-predicate sentence.
Worse, a sentence like "existence is not a predicate" is apparently of subject predicate form, thus "existence" must be presumed to denote something.
This question has divided philosophers into two classes: realists, who assert the existence of objects corresponding to abstract concepts, and nominalists, who deny the existence of such things.

A physical law or a law of nature is a scientific generalization based on empirical observations.
Physical laws are distinguished from scientific theories by their simplicity.
If the universe were purely chaotic, the existence of life as it is known would be impossible, since organized complexity is a defining characteristic of life.

Frege and Russell, among many others, for similar reasons are well-known for their view that 'exists' is not a (logical) predicate, or more precisely, not a first-order predicate, or that existence is not a property.
That is, contemporary philosophers at least are wont to treat existence as a univocal, unambiguous concept, as if the only sense of 'existence', or the only sort of existence worth talking about, were the existence of physical objects.
Though often not discussed under the heading of existence, disputes among realism, phenomenalism, physicalism, and various other metaphysical views concern what might be called the criteria for existence.

Consequently, some discussions of existence have an unclear bearing on, for example, the sense in which numbers, possibilities, and properties exist (or might be thought to exist).

 Dictionary of Philosophy of Mind - theories of color   (Site not responding. Last check: 2007-09-18)
Physics requires that if colors are properties of physical objects, then they are describable in physical terms.
Physicalism claims that colors we attribute to physical objects in color experiences are physical properties of those objects, or as I'll call them physical colors.
Hilbert (1992) argues that color constancy shows that the biological function of color vision is to detect physical object surfaces by way of surface reflectance, and that, therefore, the colors we attribute to physical objects in visual states of color are surface reflectances.

 On Gödel's Philosophy of Mathematics, Chapter II
It seems to me that the assumption of such objects is quite as legitimate as the assumption of physical bodies and there is quite as much reason to believe in their existence.
In the case of the manipulation of symbols, this in a sense reduces to the perception of physical objects, viz.
the axioms are to the mathematical objects as the laws of physics are to physical objects.

The notion of persistent physical objects is logically merely a hypothesis to explain such correlations between perceptual situations; and the common-sense belief that the objective constituents of perceptual situations are literally spatio-temporal parts of persistent physical objects is logically one very special form of this hypothesis.
The physical object which I am said to "perceive", and the properties which I ascribe to it, are again logically (though not psychologically) in the position of hypothetically postulated entities.
According to some theories physical objects consist of groups of sensa, and a physical object is perceived when a certain sensum of a certain group becomes the objective constituent of a perceptual situation.

 CATHOLIC ENCYCLOPEDIA: Existence of God
What anti-Theists refuse to admit is not the existence of a First Cause in an indeterminate sense, but the existence of an intelligent and free First Cause, a personal God, distinct from the material universe and the human mind.
This argument undertakes to deduce the existence of God from the idea of Him as the Infinite which is present to the human mind; but as already stated, theistic philosophers are not agreed as to the logical validity of this deduction.
Actual existence is certainly included in any true concept of the Infinite, and the person who admits that he has a concept of an Infinite Being cannot deny that he conceives it as actually existing.

 Simulation, Consciousness, Existence -- Hans Moravec, 1998
The brain would be physically sustained by life-support machinery, and mentally by connections of all the peripheral nerves to an elaborate simulation of not only a surrounding world but also a body for the brain to inhabit.
Physical quantities like the speed of light, the attraction of electric charges, and the strength of gravity are, for us, the unchanging foundation on which everything is built.
But if our existence is a product of self-interpretation in the space of all possible worlds, this stability may simply reflect the delicacy of our own construction---our biochemistry malfunctions in worlds where the physical constants vary, and we would cease to be there.

On the contrary, she justifies the objective existence of mathematical concepts on the intimate relation between mathematics and science: Since physics is about real things and mathematics is indispensable for physics, then mathematics is also about real things.
Just as mass, for example, is one of the properties of physical objects that is studied in physics, so also ``number'' is one of the properties of sets that is studied in mathematics.
Just as physical objects are comparable in terms of mass, so sets are comparable in terms of number: $$\ctrblock The von Neumann ordinals are nothing more than a measuring rod against which sets are compared for numerical size.

 SparkNotes: Problems of Philosophy: Chapter 2 - The Existence of Matter
The criterion for our certainty is the independent existence of physical objects, for we have identified matter with physical objects in the preceding chapter.
The object now is to establish what many philosophers suspect, that the table exists independent of our perception of it, that if we turn away from it the table is still there.
Initially, Russell reminds us that while we are doubting the physical existence of an object, "we are not doubting the sense-data, which made us think there was a table," the immediate experiences of sensation.

That people very well understand what it means to say that an object exists isn't necessarily to say one can define it.
Interestingly enough, though, only a few philosophers have given such definitions (unless one would wish to construe materialism as a theory of the meaning of 'existence' which it normally isn't).

But it is the spatial concept of physical separation that serves as the paradigm for all our notions of separation and difference.
You might not have the explicit belief that you are a physical object like a body, but in a subtle way you are still granting independent existence to physical objects.

He denies the existence of physical objects (where ‘physical object’ means something mind-independent).
“Thus we find that, although the relations of physical objects have all sorts of knowable properties, derived from their correspondence with the relations of sense-data, the physical objects themselves remain unknown in their intrinsic nature, so far at least as can be discovered by means of the senses” (p.

 Empiricist/Insturmentalist Phenomenolism:
It is important to note that holding a realist view of theories means believing that the truth of a theory of physical objects is independent of experiences and minds.
Empiricist Phenomenalism holds that our perception of physical objects is derived from our senses, and that we come to believe that physical objects exist because the theory of physical objects is the theory that best fits our empirical evidence.
One is left to wonder why Direct Realists say that the reason for belief in physical objects is the physical object, and not the sense experience.

Nonetheless, in the remainder of the positive argument, Husserl focuses on a critique of "epistemological psychologism and physicism" (85).
In other words, psychology is bound to assume the existence of physical objects as it makes any statement about the human mind.
It follows that natural sciences cannot account for consciousness and its objects, or, at least, an important part of them: "[to attribute a nature to phenomena] is the absurdity of naturalizing something whose essence [or immanent character] excludes the kind of being nature has" (107).

However, he of course numbered the missing and the additional (i.e., later added) objects, as he did not look at them as Messier's "nebulae." Erroneously, he also numbered some of the Messier objects though, and in some cases, parts of Messier objects.
Almost all of Herschel's objects (even the non-existing, erroneous entries) have also obtained an NGC number; there are only four or five exceptions.

After reviewing what skepticism does and doesn't involve, we completed formulating Descartes' two arguments for the view that the mind is a soul ‑‑ that the thinking thing (this "I" that thinks) is a nonphysical thinking substance.
We will finish setting out Descartes' metaphysics, which will include arguments for the existence of God, the existence of physical objects, and the causal interaction between mind and body.
Appealing to the distinction between formal and objective reality, the instructor formulated Descartes' argument for the existence of God, his defense of the existence of physical objects, his explanation for the occurrence of perceptual errors, and his defense of the causal interaction between soul and body.

Recall Locke’s criteria of identity for identity of substances, in particular, identity of bodies — which he takes to be identity of matter.
