On Personal Identity:
The issue of personal identity and its determents has been always an issue of concern for a lot of philosophers. John Locke was one of the philosophers who were against the Cartesian theory that soul accounts for personal identity. He stated that if the soul is the determinant of personal identity then what if two people share the same soul, and wondered if in this case they will be the same person.

There are several philosophers who criticized the Locken memory theory, and stated that it is circular and illogical. Among those philosophers was Thomas Reid. Reid was against Locke's memory theory and tried to reduce it to absurdity. He criticized his theories for several reasons. Firstly, Reid believed that personal identity is something that cannot be determined by operations, and that personal identity should be determined by something indivisible. Also, he states that Locke's main problem is confusing evidence of something with the thing itself. Finally Reid introduces the officer paradox in an attempt to reduce Locke's Memory theory to Absurdity. Reid criticizes Locke by arguing that what Locke does is confuses evidence of the thing with the thing itself, or in other words, he confuses evidence for personal identity with personal identity itself. Locke believes that memory is the best evidence for identity, if a person remembers what he does then he knows...
