18. The ideas we have belonging and PECULIAR TO SPIRIT, are THINKING, and WILL, or A POWER OF PUTTING BODY INTO MOTION BY THOUGHT, AND, WHICH IS CONSEQUENT TO IT, LIBERTY. For, as body cannot but communicate its motion by impulse to another body, which it meets with at rest, so the mind can put bodies into motion, or forbear to do so, as it pleases.
18. Bereziki espirituarenak diren ideiatzat ditugunak pentsamendua eta nahimena edo pentsamenduaz gorputza higiduran jartzeko ahala eta ahal horren ondorio den askatasuna dira.
