Synonyms

in one's right mind

Idioms  

  1. In a healthy mental state; sane and rational. For example, No one in his right mind would ski down this icy slope. This expression is often used in a negative construction, as in the example. The positive sense appears in the New Testament (Mark 5:15), where a deranged man whom Jesus helped is now “sitting, and clothed, and in his right mind.” The antonym out of one's mind, as in You must be out of your mind to swim in that icy stream, is from the same period. [c. 1600] Also see go out of one's mind.

From Roget's Thesaurus of English Words and Phrases by Roget, Peter Mark

The question remains, … what IS logic? … and what IS being in one's right mind?

From Ardath by Corelli, Marie

For to be in one's right mind causes grief: but madness is an ill; yet it is better to perish, nothing knowing of one's ills.

From The Tragedies of Euripides, Volume I. by Euripides
