All we can say that following in the tradition of Anaximander, he also disagreed with his mentor.
following in the tradition of Anaximander这句话是修饰成分，主句是he also disagreed with his mentor.为何呢？following....是修饰吗没看出来
原句如下：
Allwecansayfor certain about Anaximenes, who was probably born around 560 BCE, isthatfollowinginthetraditionofAnaximander,healsodisagreed with his mother.
看你的句子，All we can say that...这就是一个错误的结构。
原句that引导表语从句，从句的主谓为he also disagreed, 前面的following...只能是状语。
