Hoping that humans would always be reasonable was something far too foolish to hope for.
This was a maxim of the world, as well as something that was useless to say. Or, perhaps it was something useless to say that was close to a maxim of the world.
What exactly did this mean?
A maxim would be a general truth that just about everyone agreed upon. For example, physical differences between male and female, or that people would die if they were killed, or that the sun rose in the east and set in the west… These were all maxims, but were also basically useless to say, because this was all common sense that everyone understood without needing to say it.
Would hoping that humans would always be reasonable be foolish? Of course it would be.
Anyone that had any type of emotions or feelings at all would never be able to say that they would forever be able to remain logical and reasonable.
