 If determinism is true, then our acts are the consequences of the laws of nature and events in the remote past. But it is not up to us what went on before we were born [i.e., we do not have the ability to change the past], and neither is it up to us what the laws of nature are [i.e., we do not have the ability to break the laws of nature]. Therefore, the consequences of these things (including our present acts) are not up to us. (van Inwagen 1983, 16; cf. Fischer 1994, ch. 1)
