I consider the first part of Marty's Raum und Zeit, which treats of both the nature of space and spatial perception. I begin by sketching two charges that Marty raises against Kantian and Brentanian conceptions of space (and spatial perception) respectively, before detailing what I take to be a characteristically Martyan picture of space perception, though set against the backdrop of contemporary philosophy of perception. I then consider whether any contemporary philosophy of perception is equipped to make sense of Martyan space perception, and I suggest that the most promising conception is Naïve Realism. Finally, I outline a difficulty for this theoretical translation and close by detailing that what I thereby take to be a distinctively Martyan form of Naïve Realism to involve.
