''Óriginal parts'', ''identity '' and ''retip'' conundrum

If a product is produced from the exact same assembly of Materials, in the terms of a Marketing Description it is an Identical Model, and that is the requirement of the law to ensure the Model on offer complies with the materials used as advertised by the Supplier/ Manufacturer.

As said when the time of Manufacturer Refurbishment Occurs, a disclaimer might declare that the materials in the assembly may not be maintained, if new parts are to be used in the process of refurbishment.

I am sure that if an assembly of a selection of Parts belonging to a range of Cartridge Models was investigated with scientific control measures, a difference between a similar part,  when compared is most  likely to be detected, such a endeavour to match parts to this level of accuracy is not required to be carried out by the Cartridge Manufacturer, and I doubt whether such a practice has ever occurred.       

pindac , Those  are ''deep philosophical waters'' because two

different criteria are assumed. I already quoted Wittgenstein:

''for two things to say  they are identical make no sense''.

Even Quine was not able to explain the difference between

equal and identical. Frege's  problem to explain truth was 

caused by his conviction that  ''correspondence''  in correspondence

between an statement and reality make no sense because one

is linguistic and ''the other'' is not. BTW the expression ''extra

linguistic reality'' means ''the same'' . Now ''our carts''. If they are

''identical'' how  can they sound different? There are to many people

who sell their Van den Huls but there not many who sell their FR-7fz.

or Takeda's Miyabi. 

BTW are Siamese twins equal or identical? If identical what kind

of ID should they have. ?  Are two eggs identical or equal in the

sense of their property? Well there is ''property criterion'' and

meaning criterion : ''everything is identical with itself''.

According to Wittgenstein this ''says nothing''. :iucky us humans

each individual has his own such that there are no two with the

same identity. However some may look as an other(grin) 

Can a Link be supplied to the discussion where the referred to individual 'Wittgenstein' has made comments known about MC Cartridges and 'retips', this might help with eliminating Third Party interpretations, that are seemingly detracting from the subject of the thread. The content offered from the said person 'Wittgenstein' on the matter of commercial products assemblies and the consistent use of common parts whilst a range of models is being produced, appears to be suggested as being quite relevant. 

Wittgenstein was Austrian Philosopher belonging to the so called

''analytical school''. His work was ''Tractatus'' and ''Philosophical

investigations''. Alas he was not capable to formulate any theory

but made many  philosophical remarks. About 10000 in his

investigation while an normal person can remember, say, 10.

There was also one particle physics  scientist very celebrated

but I forget his name. Not however his statement: ''If I was smarter

I could remember more of those particles''.

In , uh, ''the same way'' I remember quoted statement about identity

from Wittgenstein. '' A looks like B''  may , I hope, explain uh, ''the

same cart'' in your description ? This  assumes that A and B

are not identical. In addition certainly so if they don't sound ,uh,

''the same''.

Damn you pindac, I was forced to search for an possible explanation

for Wittgenstein opinion about identity. I knew that is has something

to do with difference between properties and meaning but forget the

(damn) details. Well there is this ''huge German philosopher ''

Leibniz with his ''principle'' of identity named in Latin parlance 

among scientist back then . Just bellow aristocracy qua status.

the expressions was INDISCERNIBILIS or English INDISTINGUISHING:

My guess was '' if there are two eggs'' than obviously (?) one

can distinguish  one from the other.  But one need to know that

back than it was not polite to contradict philosopher, Certainly so

in Germany. Think of Kant . If you want to stay alive never say

whatever bad about his greatness. Wittgenstein however was not

even impresses by Russel or Frege and insulted both by

stating that ''two of whatever'' can't be identical as well that

this kind of identity MAKE NO SENSE. But he actually also

stated the same for the other CRITERION  : being identical with

one self. This according to him ''says nothing''. 

So my best members of this forum look out with identity 

of parts and other CONUNDRUM as mentioned in this thread.
