David Lewis finds a puzzle within the realm of possible objects known as the problem of temporary intrinsics. In our everyday view of objects, contractions arise with their properties. If objects are wholly present (at every moment in time) and contain within them all possible properties, how is it possible that objects, such as an apple, bear contradictory properties (being green and red)? In what follows is a discussion of this problem in detail, as well as, Lewis's perdurance solution. After the presentation of his new ontology, I will explore an objection Thompson believes severely damages the notion of temporal parts.
There are three non-negotiable theses that express some of our most firmly held beliefs and intuitions about the world in regards to persistence. First, no object can contain within it incompatible properties. Second, change involves incompatible properties. And lastly, objects sometimes persist through change. There are three broad approaches that attempt to merge all three theses into one working theory in order to resolve the tension between them. They are: perdurantism, exdurantism, and endurantism. For purposes of this paper I will discuss both perdurantism and endurantism.
Let's look at change more closely. When an object undergoes change, for instance an apple, it goes from one property (being green) to another, incompatible, property (being red). Objects have properties just in virtue of what it is like (the cat is clever) and they have properties that are partly in virtue of what other things are like (the cat is larger than the mouse) (Lewis 204). Objects appear to change from one intrinsic state to another throughout its lifespan. The job of the ontologist is to determine how this is so.

...it makes one wonder how the stages are really related to one another. That is to say, how is stage t1 identical to t2? While, Lewis does respond saying that they share causal relations (Lewis 218), it seems that four-dimensionalism is not without its worries.
Temporary intrinsics is a worrisome concern when one adopts the ontology of three-dimensionalism. The idea of an object being wholly present when we look at it is our intuition, but when we peer more closely we see a contradiction that emerges. Lewis attempts to resolve this contradiction by developing a whole new ontology that states that time is an analogy for space. While this method does dissolve the worry of temporary intrinsics, it does, however, bring forth more metaphysics concerns about the state of objects. Perhaps, as Thompson has stated, four-dimensionalism is just an overreaction to the problem.
ABSTRACT: Many philosophers have lost their enthusiasm for the concept of supervenience in the philosophy of mind. This is largely due to the fact that, as Jaegwon Kim has shown, familiar versions of supervenience describe relations of mere property covariation without capturing the idea of dependence. Since the dependence of the mental on the physical is a necessary requirement for even the weakest version of physicalism, it would seem that existing forms of supervenience cannot achieve that for which they were designed. My aim is to revive the concept of supervenience. I argue that if we construe supervenience along Davidsonian lines — as a relation connecting predicates rather than properties — then it avoids the shortcomings of the more familiar varieties.

If a two-way communicator existed across time for this to be achieved the two metaphysical considerations must be met. Firstly, Lewis highlights the that “time is one dimension of four”, in the fourth-dimensional world, suggesting that time is just as perceptible as any place and potentially where the time traveller will send the message. Second, fourth-dimensional spectrum also considers causation and possible reverse causation, that is there must be awareness for earlier events to be causally dependable on the future events, and therefore how communication will take place between two different times. Lewis argues that his grandfather paradox can provide solidarity with the past, only if a time traveller was to travel to the past, they would not be able to make any changes that may potentially lead to them never
According to the chosen priority, either object in general, or change in general, usually two types of metaphysics have been distinguished: Object Ontology and Process Ontology.
John McTaggart in his essay “Time” presents a radical argument that claims time is unreal. While the argument is interesting and has attracted much attention for his arguments, I remain unconvinced of the argument he makes. This paper will lay out McTaggart’s argument that time in unreal, critically analyze why I believe McTaggart’s argument fails and present an alternative idea about time, utilizing aspects of McTaggart’s argument.
The 'doctrine of recollection' states that all true knowledge exists implicitly within us, and can be brought to consciousness - made explicit - by recollection. Using the Platonic concepts of 'Forms', 'particulars', 'knowledge' and 'true opinion', this essay explains what can or cannot be recollected, why all knowledge is based on recollection, and why the doctrine does not prove the soul to be immortal.
Locke viewed the identity of living entities in a different light. Above, change in mass constituted a change in identity. But, in living entities a change in mass does not affect the identity of the object. Locke uses the example of the oak tree. It starts off as a sapling and grows into a huge oak tree, with a massive change in mass. That oak tree could be subjected to the cutting of branches, and the winter fall of leaves, however it still remains an oak tree because it continues the life of a tree. It maintains the same functional arrangements of components (Blackburn, 1999: 125-126). An interesting example is raised by Blackburn in assessing “how much change to tolerate while still regarding it as the same ‘thing’” (Blackburn, 1999:127). ‘Theseus’ ship’ is used to illustrate this. The ship goes on a long voyage and is in need of constant repair and maintenance. By the end of the voyage, all the components of the ship have been changed.
The what it is like to undergo an experience is essential to understanding that experience. Known by philosophers as subjective qualia, these characteristics are part of what makes a felt experience exactly that experience. If we introspect our own mental states, this seems apparent and incontrovertible. Most philosophers are unwilling to grant that subjective qualia are non-physical states, and attempts to face this problem and maintain physicalism must address arguments from qualia. While differing physical explanations for these subjective qualia exist, I will only briefly refer to them here as qualia will serve only as a means of leading the reader to the Explanatory Gap(1). The Explanatory Gap is a uniquely puzzling problem for physicalist philosophies of mind.
Physicalism, or the idea that everything, including the mind, is physical is one of the major groups of theories about how the nature of the mind, alongside dualism and monism. This viewpoint strongly influences many ways in which we interact with our surrounding world, but it is not universally supported. Many objections have been raised to various aspects of the physicalist viewpoint with regards to the mind, due to apparent gaps in its explanatory power. One of these objections is Frank Jackson’s Knowledge Argument. This argument claims to show that even if one has all of the physical information about a situation, they can still lack knowledge about what it’s like to be in that situation. This is a problem for physicalism because physicalism claims that if a person knows everything physical about a situation they should know everything about a situation. There are, however, responses to the Knowledge Argument that patch up physicalism to where the Knowledge Argument no longer holds.
This paper aims to endorse physicalism over dualism by means of Smart’s concept of identity theory. Smart’s article Sensations and the Brain provides a strong argument for identity theory and accounts for many of it primary objections. Here I plan to first discuss the main arguments for physicalism over dualism, then more specific arguments for identity theory, and finish with further criticisms of identity theory.
However, the permanent changes are only applicable to physical objects. In Descartes argument, he observes a piece of wax, from a hive, and using his judgment and senses, analyzes the structure and properties of the wax. This argument is an attempt to prove that the essential properties of things are not perceived through the senses, but through the mind. With this, Descartes reminds me as a human being to avoid being dependent to the senses. Though through matter by which we can be able to know something, depending on our senses is sometimes unreliable. The most interesting part of this discussion is that despite of the changing characteristics of physical objects, there will still be that character that will be stayed the
In this paper, I will explain and argue for two-way interactive substance dualism. Dualism is a term referred to the idea that there are only two basic kinds of things and everything real is categorized under those two things. Dualism is split into two types, substance dualism, and property dualism. Substance dualism is the idea that the mind and body are two different sorts of basic substance, whereas property dualism is our mental and physical properties are two separate types of basic properties even though they may be properties of the same thing (lecture). Branching from dualism, mind-body dualism argues that the mind and body are two separate entities. Although they are two different substances, i.e. brain/body being material and
The first idea presented in the story is that of a fourth dimension. I wasn’t exactly sure what the fourth dimension was because it is not something that is dealt with a whole lot in every day living. The story begins with the time traveler sitting in a room with some guests. We never learn what the time traveler’s name is, he is simply referred to as the time traveler in the story. I thought the explanation of the fourth dimension that the time traveler gave to his guests was easy to understand and very interesting. The time traveler explains, “ ‘You must follow me carefully. I shall have to controvert one or two ideas that are almost universally accepted. The geometry, for instance, they taught you at school is founded on a misconception.’
When I first read this topic, the word that jumped out at me was “change”. It reminded me that nothing stands still. We are all constantly moving forward, transforming, evolving and changing. We would not be able to advance if we just kept still, not wanting to move, we would get left behind. Time does not wait for anyone, the old dies and is replaced with the young and new. A bud grows into a flower and then into a fruit, a young girl changes into a woman. Morning changes to noon, and then into night and the whole cycle starts again which makes me think that no change is permanent. Change is subject to change.
