74. Space is nothing in itself, distinguished from bodies; it is only the extension of bodies: time is nothing in itself, distinguished from things. It is only the succession of things.
75. The idea of space is the idea of extension in general; the idea of time is the idea of succession in general.
76. Where there are no bodies, there is no space: where there are no things which succeed each other, there is no time.
77. An infinite space, before the existence of bodies, or outside of bodies, is an illusion of the imagination: an infinite time before the existence of things, or outside of them, is also an illusion.
78. Space is continuous: so is time.
79. One part of space excludes all others; one part of time also excludes all others.
80. A pure space, in which bodies are situated, is imaginary: a succession, a time, in which things succeed, is also imaginary.
81. That which is entirely simple has no need of space, and can exist without it: that which is immutable has no need of time, and can exist without it.
82. The simple and infinite is present to all points of space, without losing its infinity: the immutable and infinite is present to all instants of time, without altering its eternity.
