Dispassion

"Reason is the slow and tortuous method by which those who do not know the truth discover it. The heart has its own reason which reason does not know." - Blaise Pascal, Pensées (1670)

It was once considered a virtue to be dispassionate, particularly if one was, say, a scientist or an economist or a civil servant, or even, perhaps, a politician.

Today, people boast about how 'passionate' they are about some cause or other. Lots of people are 'passionate' about 'climate change.' Even the robotic Al Gore.

Pascal also wrote that "When the passions become masters, they are vices." - Pensées (1670)

He's still right about that.
