霍布斯的国际关系哲学以其从自然状态概念引伸而来的国际无政府状态为理论基础，推导出国家间会为安全而进行普遍和绝对的竞争和冲突。然而，他未看到国家间可能有、也确有的协调与合作。他还从国际无政府状态这一根本结构特征出发，断定国家不受道义约束，而只受制于自身的利益（特别是安全）需要。这同样既有其真理性，又不免片面和偏狭。他的思想对二战后的现实主义国际关系理论、特别是其中的结构现实主义有重大的意义。 Hobbes’s philosophy of international relations, based on his theory of international anarchy derived from the notion of natural state, deduces that there will be universal and absolute competition and clashes among nations for security. However, he did not see possible and definite coordination and cooperation among countries. He also proceeded from the fundamental structural feature of an international anarchy and concluded that the state is not bound by morality but only by its own interests (especially security). Again, this is both truthful and unilateral and inhospitable. His thinking is of great significance to the realistic international relations theory after World War II, especially the structural realism.
