Essence/nature/Dennett: Nothing that is so complicated that it is interesting can have an essence. (s) Reason: if it consists of several parts, it can only have developed gradually, while discarding useless parts. Therefore, it was not essential at any time. Of course, not even at the present time.
DennettVsEssentialism: E.g. has the vending machine dissolved into nothingness. Similarly: E.g. Frog: would have tried to catch food pellets in the wild just the same if they had crossed his path.
Disjunction: in some ways "fly or pellets" is a natural type of frogs. They do not naturally make a distinction between the two of them.
On the other hand, disjunction is not a natural type: it does not occur in nature.
