 Since a detailed discussion of these philosophers’ accounts of free will would take us too far afield, we want instead to focus on isolating a two-step strategy for defending compatibilism that emerges in the early modern period and continued to exert considerable force into the early twentieth century (and perhaps is still at work today). Advocates of this two-step strategy have come to be known as “classical compatibilists”. The first step was to argue that the contrary of freedom is not determinism but external constraint on doing what one wants to do. For example, Hobbes contends that liberty is “the absence of all the impediments to action that are not contained in the nature and intrinsical quality of the agent” (Hobbes 1654 [1999], 38; cf. Hume 1748 [1975] VIII.1; Edwards 1754 [1957]; Ayer 1954). This idea led many compatibilists, especially the more empiricist-inclined, to develop desire- or preference-based analyses of both the freedom to do otherwise and self-determination. An agent has the freedom to do otherwise than \(\phi\) just in case if she preferred or willed to do otherwise, she would have done otherwise (Hobbes 1654 [1999], 16; Locke 1690 [1975]) II.xx.8; Hume 1748 [1975] VIII.1; Moore 1912; Ayer 1954). The freedom to do otherwise does not require that you are able to act contrary to your strongest motivation but simply that your action be dependent on your strongest motivation in the sense that had you desired something else more strongly, then you would have pursued that alternative end. (We will discuss this analysis in more detail below in section 2.2.) Similarly, an agent self-determines her \(\phi\)-ing just in case \(\phi\) is caused by her strongest desires or preferences at the time of action (Hobbes 1654 [1999]; Locke 1690 [1975]; Edwards 1754 [1957]). (We will discuss this analysis in more detail below in section 2.4.) Given these analyses, determinism seems innocuous to freedom.
