为避免下文的朴实想法受到误解,有必要预先作出声明。我将要说的一切必须从每门具体科学的观点而不是从哲学的意义上来理解,如果不能完全从一门具体经验科学的观点来理解,那么就从适用于特定科学的一般观点来理解。假如在此所言毕竟还有些意义,那么原因不外乎两个:首先,它导源于特定学科中一个非常具体的问题;其次,形式上类似的情形在其它学科中比比皆是,而且这样的情形也根植于我们的思维工具中。但是这种见解并非先验论,而是后来才在发展过程中显现的。 To avoid the misunderstanding of the plain ideas below, it is necessary to make a pre-declaration. Everything that I will say must be understood from every concrete scientific point of view, not from a philosophical point of view, and from a general point of view applicable to a particular science, if not completely understood from a specific empirical science point of view. If, after all, there is something else, then there are no more than two reasons: First, it leads to a very specific problem in a given discipline; second, formally similar situations abound in other disciplines, The situation is also rooted in our thinking tools. But this view is not a priori, but only later in the development process.
