R??SUM???? travers l?????tude de la correspondance philosophique entre Descartes et Henry More, je souhaiterais montrer que les th??mes centraux en sont la consid??ration de la nature de l???espace et le statut de l???infini, bien que la pol??mique aborde??galement le probl??me ontologique de la distinction entre l?????tendue et la pens??e, et les questions physiques de la n??gation du vide et de l???atomisme. More rejette l???hypoth??se cart??sienne d???un univers ind??fini, qu???il consid??re??tre une mani??re d??tourn??e de postuler le caract??re infini de l???univers, ce (...) qui revient?? attribuer tout autant l???infinit???? la mati??re qu????? Dieu, d???o?? le fait que Descartes soit un mat??rialiste selon Henry More. ABSTRACT The correspondence between Descartes and More covers a diversity of each author???s fundamental philosophical views. Their polemics range over not only general aspects of physics, but also extend to cosmology and theology. On the one hand, we have God as infinite and His creation as indefinite for Descartes; on the other hand, God as extant, ubiquitous and omnipresent, and His creation as limited for Henry More. It is this last problem that constitutes the focus of my essay, strictly speaking??? the problem of the universe as infinite. (shrink)
