In this sense, system analysis is in the "grey" circumstance. That is, thinking in the "grey" way, making decision with "grey" information and taking actions with "grey" law.

从这个意义上讲，系统分析都是处在“灰”的环境中，按“灰”的方式思维，按“灰”的信息决策，按“灰”的规律行动。

To invoke alien law when it agrees with one's own thinking and ignore it otherwise is not reasoned decision making, but sophistry.
