Neither is it identical with (iii) the problem below of how to individuate instances of property determinates. Any reduction of determinable properties (such as length, mass, and electric charge) to determinate properties (such as 2.03 m long, 5.67 kg mass, and 7.12 coulomb electric charge) must be able to explain why it makes sense to add determinate lengths (or masses, or electric charges) to each other, and why it does not make sense to add determinates of different determinables (quantity dimensions) to each other. Examples: 2.03 m + 5.67 m + 7.12 m = 14.82 m; 2.03 kg + 5.67 kg + 7.12 kg = 14.82 kg; and 2.03 c + 5.67 c + 7.12 c = 14.82 c. But: 2.03 m + 5.67 kg + 7.12 c = 14.82 ???    (02) > The problems with e.g. an > absolutely determinate shade of red are clear. Consider that you have a red > car.

Just how small can be the smallest possible coloured part?    (05) As small as the smallest colored part that you are able to perceive, I would say.    (06) Best, Ingvar    (07) _________________________________________________________________ Message Archives: http://ontolog.cim3.net/forum/ontolog-forum/ Subscribe/Config: http://ontolog.cim3.net/mailman/listinfo/ontolog-forum/ Unsubscribe: mailto:ontolog-forum-leave@xxxxxxxxxxxxxxxx Shared Files: http://ontolog.cim3.net/file/ Community Wiki: http://ontolog.cim3.net/wiki/ To Post: mailto:ontolog-forum@xxxxxxxxxxxxxxxx    (08) ```
