MY SONIC LAB Cartridges

The implicit premise or assumption is based on Aristotelian
''essentialism'' . The conviction that objects have ''essential''
or ''accidental'' properties. Because of his influence in Western education this assumption is still present despite the facts that
his ''teaching'' is refuted by Galileo in physic and logic and
methodology by Frege. 
Then we have Ikeda's  cantileverless kinds as well Decca's.  

Truth versus authority. In western ''culture'' there was confusion
between those two. That is why Aristoteles ruled for 2000 years
in western education. Because of his ''authority''. 
For my American friends who are interested in ''phylosophical
questions'' I can recommend their own  Willard van Orman 
Quine about essentialism in his ''From a logical point of view'' 
( p. 22, 155 and 158). I am sure that his authority is much bigger
than my (grin).

I note that you are very invested in philosophy, logic and reason.

I was wondering what thoughts you might have to explain why some folk sincerely believe they know what a product sounds like without ever having heard it, nor the system in which the proposed purchase is to be used.

Dear dover,  I realize the limitation of grammar with ''Subject (is)
Predicate'' sentence form while all kind of comparisons we use
assume ''relational statements'' like in our forum with ''better
than,,,'';  ''more important than...'' etc. relations . Those can't
be expressed with ''subject - predicate '' sentence form, To put
this otherwise  not everything can be expressed in terms of
properties or qualities of objects. 
Take for example expression ''brother'' . Everybody thinks to know
what this expression means. But ''brother'' is not some object
with specific properties. It is actually an place in family ordering.
It depends from the extension of the family who all are brothers
and sisters. In industrial countries ''family'' is reduced to ''household''
with ''dad , mom and kids'' but in  an  agricultural society family is
much larger and consequently  more names are invented to
name each member. I myself have no ''born brother'' but do have
many brothers and sisters in Serbia related to me via uncles , ants
etc. family of my ''dad line'' and my ''mother line''. Problem with
''names'' is that thy don't have always exact reference .

Dear dover, If you mean Lew by ''some folk'' I need to explain
his way of thinking. He usually make his assertion explicit
and deduce from those other statements. He of course also
assume that if his assertion (premise) are not true than
also deduced statement can't be true. This a kind of ''self-
evident'' precaution by theoretical thinking. I can't remember
that he ever ''claimed truth'' for his statements.
