In one's right mind 🧠✅

Meaning

To be thinking or acting in a rational, sensible, and logical way.

Origin

This phrase likely stems from an older, more literal understanding of the brain's connection to reason. Historically, mental faculties were often thought to be physically located within the 'right' side of the head or body, perhaps influenced by ancient beliefs associating the right side with correctness and strength. To be 'in one's right mind' meant possessing sound judgment and rational thought, as opposed to being swayed by madness or irrationality, which might have been metaphorically conceived as residing in the 'left' or 'wrong' side. The simplicity and directness of the expression cemented its place in our language.

Can you be mentally sound but not in your right mind?
