X that defines y

1. Does "the dialectic of nature and culture that defines history" imply "the dialectic of nature and culture is defined by history" or "the history is defined by the dialectic of nature and culture"?

2. Does "insists on a recuperative erotics of the body" mean "insists on the erotic aspects of the body"?

3. Does "It was ultimately in being reduced to the body as defined by the white gaze that the black body was robbed of itself, hence the importance of celebratory images of the black body rather than simply analytical ones." mean "ultimately how white people reduced black people to their body resulted in the black body losing its identity and the preference of pleasing (sexual) images of black bodies rather than analytical images of them "?

Context:

In the photomontage The Fir-Palm, foliage of a New England fir tree grows from a tropical palm trunk that in turn springs from an African woman’s navel, the image not only referring to O’Grady’s cultural background, but also to the split between nature and culture that allowed the colonial gaze to subjugate other races as being closer to nature and therefore inferior. However, this work not only shows the dialectic of nature and culture that defines history, but also insists on a recuperative erotics of the body. It was ultimately in being reduced to the body as defined by the white gaze that the black body was robbed of itself, hence the importance of celebratory images of the black body rather than simply analytical ones.
