### A Thought Experiment by and on You

Please conduct the following simple (series) of thought experiment(s) by and on yourself (X): Take your actual (current) date of birth (DOB(X)=x) and now construct/compute a date exactly one year earlier than your DOB. Got it?

Ok, now throw away your old DOB and focus on this new, derivative date (x-1) and try to imagine that x-1 is your DOB. Got it? [1] .

The question to ask yourself now: Would this person, X, born on this new DOB, x-1, but ‘ceteris paribus’, be still you, X?

Once you have an answer (yes, no, don’t know, it depends …) take now the date exactly one year later than your original DOB, x+1 and ask the same question.

Now make the difference +/- 2 years, 3 years, 4 years, 5 years … and ask the same question. Stop when you get the same answer 2-3 times in a row or notice if you change your position with different numbers. Register whether you think differently if the test scenario is earlier or later than your actual DOB.

In what follows I will delineate some potential answers to this thought experiment. These answers won’t follow any derivative historical positions and only grew out of me thinking about the possible logical space and interviewing quickly several acquaintances of mine, yet they (probably) might coincide with some actual philosophical accounts that could be given. I am looking for ways to make the scope of these possible answers comprehensive, to hash out the logical space.

I start with the conservative, negative positions to move towards the more permissive ones. Continue reading “DOB and personal identity: could we have been born couple years off? Part 1”
