Good Definition Essay

Good Essays
A philosophically good definition can be very hard to come by for most concepts, ideas, and even simple words. The reason for this is because in order to be considered a good definition in the philosophy world it must follow three basic rules. The three rules, in short, are that it must not be just a bunch of examples, it must contain the essence of what is being defined, and lastly the definition and its concepts must be clearer than the word being defined. It may sound simple at first however, I will attempt to form a definition for the word “planet” and show you how difficult it can really be. For the first rule, it cannot be just a bunch of examples, the emphasis is highlighted on the word “just.” It is more than acceptable to use examples however it cannot only be of examples. For example, with the …show more content…
The definition must contain the essence of what is being defined. The essence, in our example, is really what makes a planet a planet. In order to test for this you must make sure the definition is neither too broad nor to narrow. For example, if I say that a planet is an object in space that orbits a star it sounds like a decent definition. However, this definition includes more than just planets. Many other things, such as moons, asteroids, and random debris all commonly orbit stars. These items are not planets so the definition would be deemed “too broad.” On the other end of the spectrum, we can try to be more specific and say that a planet is a large, solid, object in space with its own moon or moons that orbits a star. This seems like it covers the bases of a planet but its leaving out too much. The word “solid” itself eliminates too many planets such as the gas giants in our own solar system. According to this definition, Jupiter, Neptune, Saturn, and Uranus are all left out because they are made of gas and therefore not “solid.” This goes to show how difficult the second rule can

    Jupiter has barely any gravity compared to Earth, which would be a big change if intelligent life would try to live there. The average temperature of the clouds on Jupiter is around negative 224 degrees Fahrenheit. Jupiter’s atmosphere is made up of mostly hydrogen and a small amount of helium (Exploring Life’s Mysteries). Considering the atmosphere and temperature intelligent life would never be able to survive on…

    However, the designation of dwarf planet is a stronger designation because Pluto actually orbits the sun. Certainly, Eris has a very chaotic orbital range, but the gravity of the sun is continually affecting the orbit of these objects,, which them objects within the solar system. This is another reason why Pluto should be called a dwarf planet, since it has a far-reaching orbit around the sun. The previous definition of debris in the transneptunian region also makes objects, such as Pluto, far larger than the large icy objects that do not have the same shape as a spherical planetary object. Once gain, the fact that Pluto orbits around the sun and the similar shape it shares with larger planets is a rationale way to describe a dwarf planet.…

    14. If Jupiter did not exist, the threat from asteroids might be much smaller, since the objects that make up the asteroid belt might instead have become part of a planet. On the other hand, the threat from comets might be much greater. By catapulting asteroids and comets in Earth’s direction, Jupiter and other jovian planets have caused cosmic collisions that helped shape Earth’s destiny. 25.…

    The shock is closer to the planet and it is also weaker than would be expected from an ideal gas interaction with a perfectly reflecting obstacle. A problem is that the magnetosheath can interact directly with the neutral atmosphere through charge exchange and photonization. This removes the momentum from the flow, but the problem is also that both processes (charge exchange and photonization) add mass to the solar winds since the high altitude of the neutral atmosphere isn’t mainly hydrogen, but hot oxygen which has more mass. Venus also has a magnetotail but for a different reason. The thing is that the mass loading in the magnetosheath slows the…

    N. Tyson is one such individual. Tyson (2003) claims “To declare that Earth must be the only planet in the cosmos with life would be inexcusably egocentric of us” (para. 2). This means the absence of alien life in the universe is even less probable than the possibility that alien life does exist in some undiscovered corner of the galaxy, given how large the universe is and how diverse the environments of undiscovered planets could be. Tyson also sites the diversity of life on Earth as possible evidence of the diversity of alien species already in existence given how each form of life on earth has a drastically different appearance and method of survival when compared to another form of life from the same planet.…

    When a spacecraft leaves the Earth’s orbit, the gravitational force of the Earth is no longer significant and Mars is too far away so its gravitational pull has no influence either. The only object that exerts a substantial force of gravitational attraction with the spacecraft is the Sun. Because of this it is called the 2 Body Problem. It can be demonstrated using Newton’s Law of Gravitation that the orbit in a 2 Body Problem is a conic. What could be asked now is, what is the shape of the planets orbit?…

    One is their limited scope. Currently, habitable zones are defined solely by distance from a star, but there are other factors that could determine whether or not a planet could hold liquid water. Venus, the hottest planet in the solar system, actually falls within the Sun’s habitable zone; Mars, which falls well outside the habitable zone, has substantial evidence (in the form of dry riverbeds and floodplains) that there was once liquid water on its surface (Tyson, 210). The difference between the two is atmosphere. Venus has a thick carbon dioxide atmosphere that prevents almost all of the incoming solar radiation from leaving again (Tyson, 210).…

    [1] The underlying argument for the existence of dark matter, proposed by Zwicky himself, was that in order for such large clusters of galaxies to be held in place, there must be extra mass in these galaxies that we cannot see. The lack of this extra mass would instead cause these clusters to scatter away from each other. [2] In simpler terms, there seemed to be an undetectable force that acted as a gravitational field, keeping the galaxies spinning within the cluster. Since this matter emitted no form of radiation on the electromagnetic spectrum, it emitted no light. Ergo, “dark” matter.…
