[relative space and time, treated as one system]

19 ideas
Space and time are the order of all possibilities, and don't just relate to what is actual [Leibniz]
Space and time are purely relative [Leibniz]
If space and time exist absolutely, we must assume the existence of two pointless non-entities [Kant]
If all empirical sensation of bodies is removed, space and time are still left [Kant]
Space alone, and time alone, will fade away, and only their union has an independent reality [Minkowski]
Mathematicians don't distinguish between instants of time and points on a line [Russell]
Space-time arises from the connection between measurements of space and of time [Einstein, by Farmelo]
We can't think of space-time as empty and propertyless, and it seems to be a substratum [Martin,CB]
Relativity is as absolutist about space-time as Newton was about space [Coffa]
Space-time is indeterminate foam over short distances [Close]
Time, as it appears in standard modern science, is bad verificationist metaphysics [Smith,Q, by Le Poidevin]
