is it justifiable to believe that anything that could be true, actually is true? If not, why not?
Perhaps by limiting the question to things that
could be true, the assumption is they actually
are true? For example, an apple can
not be an orange. By discarding all things that
can't be true, aren't we left with only things which
are true?
Certainly we
should believe things which
are true. The difficulty is determining what things these are.
In my view, it is justifiable to also believe things that have good evidence based on philosophical reflection and philosophical analysis. Also, in my view, revealed religions and revealed spiritual paths are not trustworthy sources of knowledge and truth.
