“Integrity without knowledge is weak and useless, and knowledge without integrity is dangerous and dreadful.”
– Samuel Johnson
Dr. Johnson (1709-1784) was an English poet, playwright, essayist, moralist, literary critic and biographer.
He was a devout Anglican and a member of the Tories, who were later succeeded by the Conservative Party.
In many ways integrity is another form of honesty, or adherence to moral values.
Knowledge is essential to acting with integrity because taking action is a sign that we believe in what we are doing and action materializes integrity.
Without knowledge we can believe and act foolishly; staying current is important to being honest with ourselves and others.
In the second half of the quote there is a political reference to absolute rule: a lack of honesty in our dealings while holding on to what we know awakens a sense of dictatorship.
Integrity and knowledge thereby come together to manifest truth about the individual and his/her choices in what to believe.
