I looked it up on Wikipedia and got this:
Ontical refers to a particular area of Being, whereas ontological ought to refer to Being as such.
I also read the above, but I don't even think I understood the answer.
But this is so vague that it doesn't make any sense. Does "ontical" mean observing something and determining at it's surface level, while "ontological" mean what it is in relation to Being, for example, determining its purpose?
