Question

If over time you replace parts on a car, at what point does it stop being the same car you bought? How many parts do you need to replace to make it a new car?

Answer 1

Replacing parts on a car does not change its identity as long as its essential properties remain the same.

Step-by-step explanation:

Replacing parts on a car over time does not change it into a new car. The concept of identity in philosophy can be applied here. The identity of an object is determined by its essential properties, not its accidental properties. The essential properties of a car are its overall design and function, not the specific parts that make it up. Therefore, even if you replace all the parts of a car, it will still be considered the same car as long as its essential properties remain the same.

For example, imagine a car with a red exterior and a V6 engine. If you replace the engine, the color, and even the seats, it will still be considered the same car as long as it retains its essential properties of being a car with a certain design and function.

Therefore, there is no specific number of parts that need to be replaced to make it a new car, as long as the essential properties remain unchanged.
