宏观世界的本质，范例认为，是“相对性”。因为范例首先定义了宏观世界的根本
属性是，“物质”的存在，因而“一切运动都是物质的运动”。物质形成的特性之
一是时空二个维度的存在。物质的“有限性”和时空的“有限性”，从根本上决定
了物质是相对的，既，有限的。所以，范例认为宏观世界的“一切”都是物质，而
物质的存在，如同时空的特性一样，都是相对的。换句话说，事物的发展是有阶段
性的。当事物发展到以“物质的状态”存在的时候，其特征是“时空的维度”出现
了(还有其他维度暂不表)。事物发展到这个阶段，也仅仅是在这个阶段，事物就变
成了“相对”的了，我们称其为“物质”。这个物质的称谓，是对事物状态的一个
“定义”。用莱不尼兹的话说，叫“实心的单子”(内部没有空间存在)。这种对事
物的定义反映到理论中，如几何学的定义时，我们就有了欧几里德的几何学定义：
“Euclid's Elements，Definition 1“A point is that which has no part.”
Definition 15
A circle is a plane figure contained by one line such that all the straight
lines falling upon it from one point among those lying within the figure
equal one another.
Definition 16
And the point is called the center of the circle.
Definition 17
A diameter of the circle is any straight line drawn through the center and
terminated in both directions by the circumference of the circle, and such
a straight line also bisects the circle.
Definition 18
A semicircle is the figure contained by the diameter and the circumference
cut off by it. And the center of the semicircle is the same as that of the
circle.
Definition 20
Of trilateral figures, an equilateral triangle is that which has its three
sides equal, an isosceles triangle that which has two of its sides alone
equal, and a scalene triangle that which has its three sides unequal.
