A philosophical zombie (also called a p-zombie) is, in philosophy, a thought experiment that plays into our ideas about consciousness. Basically, a p-zombie is a person who looks and acts like any other person, but who doesn’t have consciousness. There are two different versions of a p-zombie:
The first version is only a functional p-zombie. This is a zombie that looks and acts identically to any human, but that internally is not identical (the physical construct is different). You can think of such a p-zombie as a cyborg that from the outside looks and acts identically to a human (acts based on input and data received), in which the program/cyborg outputs exactly what a person might have done, but never truly experiences consciousness like a person does. The point about this type of zombie is that it is not physically identical to a human.
The next version is both a functional and physically identical p-zombie. In other words, it’s as if we were to duplicate your entire physical structure, without the consciousness existing, yet the zombie would still do everything you would have done through only the physical processing but without the consciousness as a part of such.
