Anatta seems to be one of the trickiest subjects in Buddhism, not least because there is a very wide range of theories across the different traditions. Some traditions literally claim nothing exists (the solipsist position?) whereas some are very clearly stating “not Self, not No-Self” ie some middle position that should probably be understood contextually against Hindu notions of eternal self that were the ground truth at the time of Buddhism’s formation.
I think the “traditional” Buddhist position is something fairly similar to Hume’s view as Bundle theory.
