There is a popular claim that rationality should be reformulated from time to time. Here I argue that the meaning of human rationality must be considered one more time, because the dichotomy between the intellect and emotions is deceitful: the intellect, responsible for rational thinking, can be emotional, and emotions can be rational. In the paper I examine the role of emotions in the following types of rationality: 1. ecological rationality, where S is rational iff S is acting in accordance with its nature, i.e. iff its activity is adapted to the environment in which S lives; 2. causative rationality, where S is rational iff S’s action is appropriate to the reason that causes it; 3. teleological rationality, where S is rational iff S’s action is purposeful; and 4. effective rationality, where S is rational iff S’s action aims to optimize results.
