The important thing to note here is what Winthrop considers to be the threat: “our pleasures and profits”. Colonies were founded to make money. Everyone knew that. And even the Puritans would have to repay their investors. They were business people, many of them London merchants, and they would set about creating industry in New England. They were also normal people who loved dancing, music, alcohol, sex, and love, and they would enjoy all those things in their new land. Being a Puritan was not about denial. It was about balance. Enjoy without attachment, enjoy without letting pleasure become your master—this was the Puritan ideal
