Common Assumptions
Realism is a tradition of international theory centered upon four propositions.
1. The international system is anarchic
- There is no actor above states capable of regulating their interactions; states must arrive at relations with other states on their own, rather than it being dictated to them by some higher controlling entity.
- The international system exists in a state of constant antagonism (see international anarchy).
2. States are the most important actors.
3. All states within the system are unitary, rational actors
- States tend to pursue self-interest.
- Groups strive to attain as many resources as possible (see relative gain).
4. The primary concern of all states is survival.
- States build up military to survive, which may lead to a security dilemma
In summary, realists think that humankind is not inherently benevolent but rather self-centered and competitive. This perspective, which is shared by theorists such as Thomas Hobbes, views human nature as egocentric (not necessarily selfish) and conflictual unless there exist conditions under which humans may coexist. This view contrasts with the approach of liberalism to international relations.
Realists believe that Sovereign states are the principal actors in the international system, and special attention is afforded to large powers as they have the most influence on the international stage. International institutions, non-governmental organizations, multinational corporations, individuals and other sub-state or trans-state actors are viewed as having little independent influence. States are inherently aggressive (offensive realism) and/or obsessed with security (defensive realism), and that territorial expansion is only constrained by opposing power(s). This aggressive build-up, however, leads to a security dilemma whereby increasing one's security may bring along even greater instability as an opposing power builds up its own arms in response (an arms race). Thus, security becomes a zero-sum game where only relative gains can be made.
Realists believe that there are no universal principles with which all states may guide their actions. Instead, a state must always be aware of the actions of the states around it and must use a pragmatic approach to resolve problems as they arise.

Famous quotes containing the words common and/or assumptions:
“I am now old enough to make common cause with my predecessors against my successors.”
—Mason Cooley (b. 1927)
“All of the assumptions once made about a parent’s role have been undercut by the specialists. The psychiatric specialists, the psychological specialists, the educational specialists, all have mystified child development. They have fostered the idea that understanding children and promoting their intellectual well-being is too complex for mothers and requires the intervention of experts.”
—Elaine Heffner (20th century)
