Often we might tell ourselves that we're doing something for an altruistic reason, while in our gut we don't realize until later that we're really doing something that looks like it could be for very selfish reasons. Also, human brains are enough of a kludge that we can act for different reasons. Cooperation is helping others in a way that also helps oneself: it's selfish and altruistic.
