  A second, more philosophical, line of attack pivots on Leibniz’s  commitment to the Principle of Sufficient Reason (PSR). In  the present context we can understand the PSR as demanding that there be  some reason for God’s creating the world in one way rather than  another since “A mere will without any motive, is a fiction,  not only contrary to God’s perfection, but also chimerical and  contradictory” (Fourth Paper, paragraph 2; G  VII.371–2/Alexander 36). Leibniz argues that if the PSR is granted,  the apparent possibility of absolute space and time can be  undermined. For, on the supposition that God creates the world in an  infinite, homogenous, absolute space, there could be no reason for  his creating the world oriented in one way with respect to that space rather than another way – that is, there could be no reason to  prefer the world situated in one way rather than, say, rotated in  space by ninety degrees. Since the supposition of absolute space thus leads to a violation of the PSR, the supposition itself must be  rejected as chimerical or confused according to Leibniz. Similarly,  on the supposition that God creates the world in an infinite,  homogenous, absolute time, there could be no reason for God’s  creating the world at one time rather than at another time. Again,  since the supposition leads to a violation of the PSR, Leibniz  maintains that the supposition itself must be rejected as chimerical  or confused.
