People are zealous for a cause when they are not quite positive that it is true

Summary

This quote suggests that individuals tend to be extremely passionate or fervent about a cause or belief when they have some level of doubt or uncertainty about its truthfulness. When there is complete certainty, there may be lesser enthusiasm as there is no need for further validation or conviction. However, when there is a hint of doubt, people may exhibit heightened eagerness and zeal to prove themselves right or to persuade others, making them more committed and dedicated in their pursuit of that cause.
