Abstract: Kit Fine developed a logic for different concepts of ground: weak full ground, weak partial ground, strict full ground, and strict partial ground. He claimed that one can define all other concepts of ground in terms of weak full or strict full ground. Particularly, he claimed that weak and strict full ground are inter-definable. He proposed the definitions as follows: strict full ground is irreversible weak full and weak full ground is nothing but preservation of strict full ground. Here, I argue that this interdefinability claim has problems. I first discriminate between two non-equivalent criteria for interdefinability: that some appropriate biconditionals are theorems of certain formal systems and that there are two formal systems for the two concepts in each of which the logical behavior of the other concept can be manifested. Then, I argue that based on these interdefinability criteria at least one of Fine’s proposed definitions fails. The conclusion is disjunctive: either there are other unknown definitions for these two concepts of ground in terms of each other or these two concepts are primitive.
