The mechanisms which motivate cooperation in any form of human endeavour, as Bernard Williams explains elsewhere in this volume, comprise four basic elements: coercion, interests, values, and personal bonds. People, that is, may decide to cooperate (1) for fear of sanctions; (2) because cooperation enhances their mutual economic interests; (3) because they have general reasons, whether cultural, moral or religious, to believe that cooperation is good irrespective of sanctions and rewards; and finally (4) because they are related to one another by bonds of kin or friendship.

XREF: This four-part framework echoes familiar motivations-of-cooperation theories (coercion, self-interest, values, kinship), connecting to game theory and social contract thought.
