Abstract
The two challenging questions of the article are: (a) Where does the normativity of our speaking, thinking, and acting come from? (b) How does bounded normativity function as an antidote against cognitive and epistemic vulnerability and relativism? The article is divided into three sections: (i) It is specified what challenges and vulnerabilities a non-foundationalist justification and normativity has to meet. (ii) A three-dimensional conception of normativity and of responsibility is developed based on our human triangular relations to other persons, to the world, and to ourselves. (iii) The Principle of Reflective Equilibrium is introduced as a principle of rationality, and it is shown how this principle generates reasonable justifications under the conditions of a variety of vulnerabilities.
