Quickwrite: Is Bob Still a Person!?

              If Bob gets ran over by a bus one day, and has to replace his old crippled arms and legs with fake plastic ones, Bob is still a person and Bob is still Bob. If Bob gets ran over by a second bus and has live as a head for the rest of his life, Bob is still a person and Bob is still Bob. If for some reason Bob manages to get ran over by a third bus and has to live as a brain for the rest of his life, Bob is still a person and Bob is still Bob. If then Bob is ran over by a fourth bus and has to live as cells and DNA particles until he is cloned, Bob is no longer a human being, and Bob will not be himself anymore. No matter what happens to him, Bob will remain a human being despite of his physical changes.
          
              If Bob's arms and legs are replaced with plastic ones, he obviously hasn't changed much. His thoughts and memories are the same, although his thoughts about life have. It's the same thing when he is a head, he only changes physically. When Bob lives as a brain, he still has the same thoughts and the same memories, even though he looks totally different than other humans. Scientists would have connected his brain to a computer so that they can actually see everything that's running through Bob's mind. By doing this, Bob would be able to communicate with others through his thoughts - even if Bob has private thoughts. However, when Bob is hit by a fourth bus and has to be cloned, that clone is not a person, and it is definitely not Bob anymore. The reason for this is because anything that has to be made in a laboratory that involves tests, chemicals, and machines is most likely to not be a real person. A person is made naturally, not in labs. And if Bob is cloned, he is no longer a person. If Bob is not a person anymore, then i guess you can easily say that he is no longer Bob. There can only be one Bob, only one human being with its own emotions and characteristics that no other human (or thing) can have. I doesn't matter if Bob's clone has the same memories as the real Bob, the clone is just a copy made in a lab. So when it gets to the point where Bob has to be remade, Bob is not a person, and Bob is not Bob.
