... friction , we neither gain nor lose anything by the machine . All that we do is to transmute the energy into a more convenient form - what we gain in power we lose in space ; but we are willing to sacrifice space or quickness of motion ...

Página 217 - When, as in pure feeling — pleasure or pain — we change to the subject attitude from the object attitude, we have undergone a change not to be expressed by place ; the fact is not properly described by the transition from the external to the internal, for that is still a change in the region of the extended. The only adequate expression is a change of state : a change from the state of the extended cognition to a state of unextended cognition.
Página 212 - From the ingress of a sensation, to the outgoing responses in action, the mental succession is not for an instant dissevered from a physical succession.
Página 135 - Aristotle decides that there is no void, on such arguments as this:' — In a void there could be no difference of up and down; for as in nothing there are no differences, so there are none in a privation or negation...
