English philosopher, statesman, and author Francis Bacon (1561–1626) wrote an essay entitled Of Suspicion, in which he stated that suspicions need to be repressed and well-guarded, because otherwise they will cloud the mind, and cause a ruler to move towards tyranny, due to the fear that his subjects are conspiring against him, and a husband to become jealous and fearful of his wife's interactions with other men.
English Renaissance dramatist, poet, and actor Ben Jonson (1572–1637), a contemporary of Shakespeare, described suspicion as a "black poison" that "infects the human mind like a plague".
Samuel Johnson (1709–1784), an English author and essayist, called suspicion a "useless pain" in which a person has a belief that a formidable evil lies within all of their fellow men.
The Scottish poet and a lyricist Robert Burns (1759–1796) called suspicion a "heavy armor" that impedes humans more than it protects them.
Mahatma Gandhi, the political and spiritual leader of the non-violent Indian independence movement, warned that if suspicions arise about any of a person's motives, then all of their acts can become tainted with this mistrust and uncertainty.
