Truth and Justice in Spinoza’s Theological–Political Treatise and the Ethics

Spinoza’s philosophy argues for the freedom of individuals as singular beings in the state. This freedom is not perfect yet immanent. Freedom—according to the Ethics—is a consequence of true knowledge and virtue, which must be able to develop and can only be realised gradually. The state and the laws establish the framework that makes this freedom possible. Freedom and true knowledge are basic concepts of the metaphysical system. Justice, however, appears as a legal and political concept in Spinoza’s thought, which the philosopher did not discuss in depth. Nevertheless, the concept of justice has a specific significance in the philosophical context in which it occurs in the TTP—especially in the wisdom of King Solomon—and in the Ethics. Justice, on the one hand, strengthens harmony, security, and freedom. On the other hand, the freedom to philosophise forms a condition for justice to develop according to reason. The knowledge that justice has a importance in Spinoza’s thought is consistent with the complexity of his philosophy and makes its understanding more complete.
