【多选题】在批判了数不足以解释万物的质料因之后,汪子嵩老师提出了进一步的批判,讨论数作为量的统一性的抽象原则是否真实地存在。再次,从科学研究的特点出发,汪子嵩老师分析了数学对象到底如何存在的问题。以下说法正确的有:( )

数学和自然科学都是从具体事物中分出某一方面来进行研究，比如，物理学只研究事物的运动方面，数学只研究事物的大小和数，几何学只研究事物的点、线、面、体等，而不考虑这些具体事物本身其他方面的属性

D.
爱利亚学派和柏拉图已经知道一般是永恒的、不变的、只有理性才能认识的，而个别事物却是有生灭的、变化的，是感觉的对象
E.
爱利亚学派和柏拉图认为由理性所认识的一般——数、存在、理念——应该是最高的实在，是比具体事物更真实的存在，所以它们应该在具体事物之外，在它们之上，高高在上地独立存在着，像具体事物一样地具体存在着，亚氏继承了这些思想
