Query: One of the dumbest ideas ever

The books represents that a mathematical observation is to some extent dependent on the culture of the observer. This is, at best, a misrepresentation. An equilateral triangle does not change in properties, no matter what the culture of the observer. Two + Two will always equal four. One of the most useful aspects of mathematics is that it is not relative to the culture of the observer. What is mathematically true remains true. If two observers do not agree about a mathematical property, one is wrong or incomplete. It may be that it is the European view that is wrong, I am sure that not all mathematical truth is known yet. It may never be. What is true about mathematical observation is not variable with culture.
