o be in existence. As for the last question, no one knows for sure how the mind works. Time and time again, people have pondered over such fascinations.Among these people was John Locke. Locke believes that everything has an existence. In order for it to be something, it must evolve into existence, be in existence, and then abandon its existence. Everything must have a distinct beginning and a distinct end. Of course, he followed up on this statement by saying that something cannot have more than one beginning. Locke states that if something were to exist for sometime, then its existence ends, and then it returns to exist again, then that something that existed for the second time is not the same as that something that existed the first time. The two would be completely individual of each other, each having their own existence. These theories have been known as Locke's Principles.In addition, Locke also discussed the differences between numerical and qualitative identity. In order for two things to be numerically identical, they must have shared the same past and be the exact same thing. Where as for two things to be qualitatively identical, they need only be physically identical. Although two laptops have the same physical properties, they are not numerically identical because they are not the same token. They are, however, qualitatively identical because they have the same physical properties. There were other individuals like Locke, but came to different conclusions about one's existence. Those with Lockean beliefs claimed that for two things to be numerically similar, they would have to have shared the same pass and be the exact same thing. Those with Cartesian beliefs declared that for two things to be the same, they only needed to share the same soul. Of course, this is obvious, because as of now, no one has been able to change, switch or even modify one's soul. When that ability is developed, a Cartesian believe...
