Your views above are shallow and narrow which are based on ignorance of higher philosophical deliberations.
Note I mentioned ‘senses’ or ‘perspectives’ and you are totally blur on this critical matter. Can’t see that 500 pound gorilla?
What you have argued and presented based on the ‘Ship of Theseus’ thought experiment is based on the common sense [vulgar] and conventional perspective which is very basic.
There are many perspectives to reality but you are only capable of dealing with the vulgar [common sense] and conventional perspectives. Why? There is a psychological reason for that.
In the above you are merely playing the ‘language game’ [Wittgenstein] and not dealing with reality [emergence not the thing-in-itself.]
The only constant is change.
If you view at any thing in terms of the highest precision of reality, that thing-X is a different thing at every nano-second. e.g.
For the same thing at the conventional perspective, say a cup of water of H20 molecules.
At minute t1, that cup of water has 1,000,000 H20 molecules [say]
Let say, we add another 200,000 h20 molecules every minute.
At minute t2, that cup of water has 1,200,000 H20 molecules
At minute t3, that cup of water has 1,400,000 H20 molecules
At minute t4, that cup of water has 1,600,000 H20 molecules
At minute t5, that cup of water has 1,800,000 H20 molecules
Now what you see is the ‘same’ cup of water in the common sense and conventional sense, but in terms of the number of h2o molecules and mathematics how can you insist 1,000,000 H20 molecules is the same as 1,200,000 H20 molecules, is the same as 1,400,000 H20 molecules, the same as 1,600,000 H20 molecules?
At the higher level of precision, even at micro-changes at nano-second of any thing within a thing, it it a different thing, A [was at t1] is not A [was was at t1] anymore, rather it is now A++ [as at t2]
The above higher precision perspective is applicable to ‘Ship of Theseus’ and similar examples, the ‘Ship of Thesus’ is the same ship in the common vulgar and conventional sense BUT from a more higher and realistic perception, it is a different ship in terms of materials, molecular structures, mathematics, chemistry, physics, biology, time [t1, t2,] etc.
If a virus can talk, it will tell you it is a different ship in terms of the virus and various perspective.
Are you fearful of reality that you want to be an ostrich to avoid the higher perspectives of reality?
As I said, it is your lack of philosophical education that is leading you into making ridiculous assertions (then followed by even more).
You wish to replace all existing religions with your own, yet obviously haven’t a clue as to the real situation or need.
Don’t jump to conclusion too fast as in the above you are describing yourself.
