这一句如何理解和翻译

luhmann

Once the productive tautology reached this stage, one had to
look around for a remedy. Understanding of the problems of
structured complexity had increased at almost the same time so that
was what one fell back upon. This theoretical development then
gave impetus to the transition from the paradigm of system/environment
to the paradigm of self-reference.

一个生产性的循环定义达到这一阶段，我们就必须寻求一个补救办法。几乎同时，我们对结构化复杂性问题的理解得到加强，因此，很显然我们可以再讨论这个问题。这一理论发展则为从系统/环境范式向自参照范式的转换提供了动力。

以上理解是否妥当，就教于方家。
