The quote just saying that he feel like he belong to the human race itself more strongly than any culture/nationality.
The correct answer to this open question is the following.
The English colonies in North America were part of a larger Atlantic community in that English people were the ones that decided to leave Britain for different reasons in order to start a new life or in pursuit of better opportunities to make money. Different reasons for different kinds of people.
For instance, the case of the founders of the Jamestown, Virginia colony of 1607. They were sponsored by the English corporation, the London-Virginia Company to make the trip to the Americas, work the land and exploit the raw material and make a profit. But they were still part of a larger Atlantic community.
Or the case of the Puritans that arrived at the coast of North America in 1620 to found the Plymouth colony. They were strict religious men and women that left Britain due to the religious persecution of the Church of England. They opted to make the trip to establish a new place to practice their religious teachings freely.
