Are Grounding and Naturalness Related?

Grounding and Naturalness have been two important concepts in the Metaphysician's toolbox. They are both used to cash out the notion of fundamentality; that is, proponents of both concepts propose certain criteria for counting a property/fact as more fundamental than another. In this paper, I will explore whether there is any plausible systematic connection between the criteria the two concepts offer for fundamentality and argue that there is none. In the end, I suggest that we should stick to one consistent use of naturalness first and then explore further which concept offer a better notion of fundamentality.
