As I was running out to the pet store last night to grab an e-collar for my cat, the thought occurred to me that it might be fruitful to see if the transcendental aspect of Kant’s metaphysic could be married with realism. What follows are various other thoughts that occurred to me on this subject.
What would a transcendental realism be concerned with? Well, as I’m thinking of it, it would be a metaphysic concerned primarily concerned with the following: what are the conditions that make empirical study of the world possible? So in this sense, it’s more of a metaphysic of science. How is science possible? That’s a key question.
To polish the question a bit more: how must the world be in order for science to have proceeded as it has? Two things that come to mind are the issues of causality and universals – laws of nature would probably fit in here under both of those. So what would TR (tentatively) say here?
Well, causality, of one form or another, seems to be necessary for any empirical science to get off the ground. But causality is a metaphysical, and not empirical, category (here we can follow Hume’s insight without committing ourselves to his conclusions). We can’t study causality under a microscope. But if causality is a real feature (albeit a metaphysical feature) of the world, the question we need to ask is how exactly is causality ‘mediated’ through experience (here I wonder if modalities have a role to play)? Here’s a possible answer (not THE answer, but merely a way in which the question might be answered on this view):
Causality is a real feature of the world with both objective (transcendental) and subjective aspects – so it’s a bottom up/top down feature. Causal structures are mediated through and reflected by the empirical world and empirical study. This allows for for the conditions of study, science, etc. This view effectively thinks backwards from the given of our experience, but an argument seems to be needed that I don’t have at the moment.
So I suppose a map of this view would look something like this:
Reality———->causal structures———->experience of reality———->causal concepts———->allow empirical science
I’m not hugely satisfied with this yet, but the raw material for a decent metaphysic is here, at least.
