I have been learning about the modal operators of modal logic and it's truth evaluations in different contexts. For instance:
$$\Box A \to A$$ Would be false in Deontic logic, but true in Alethic logic. However, I am struggling to understand the following concept:
$$\Diamond T$$
By the definition of the diamond this means that it is possible that true holds, but what is the meaning of this? Does this mean that there are worlds where true might be false? And what would the meaning/truth assignment be in different contexts?
