  These are lectures notes prepared for a series of seminars I am invited to
give at Princeton Philosophy Department in November 2024. They cover the
conceptual structure of quantum gravity, the relational interpretation of
quantum mechanics, the structure of time, its orientation and the openness of
the future, the physical underpinning of information and meaning, and some
general considerations on the fact that concepts evolve, on perspectivalism and
anti-foundationalism.
