The right merchant is one who has the just average of faculties we call common sense; a man of a strong affinity for facts, who makes up his decision on what he has seen. He is thoroughly persuaded of the truths of arithmetic. There is always a reason, in the man, for his good or bad fortune in making money. Men talk as if there were some magic about this. He knows that all goes on the old road, pound for pound, cent for cent -- for every effect a perfect cause -- and that good luck is another name for tenacity of purpose.
— Ralph Waldo Emerson

If you deny any affinity with another person or kind of person, if you declare it to be wholly different from yourself
Ursula K. LeGuin affinity quote

Love is the affinity which links and draws together the elements of the world... Love, in fact, is the agent of universal synthesis.
— Pierre Teilhard de Chardin

It is wrong to think that love comes from long companionship and persevering courtship. Love is the offspring of spiritual affinity and unless that affinity is created in a moment, it will not be created for years or even generations.
— Kahlil Gibran

Most of the ancestors that I can trace were born here in the United States of America. And then it goes back to slavery. And I'm sure my ancestors go all the way back to Africa, but I feel more of an affinity for America than I do for Africa. I'm a black man in America.
— Herman Cain
