When in 1692 Locke asks his friend, William Molyneux, to comment on the first (1690) edition of the Essay, Molyneux expressly worries that Locke’s E1 account of freedom appears to “make all Sins to proceed from our Understandings, or to be against Conscience; and not at all from the Depravity of our Wills”, and that “it seems harsh to say, that a Man shall be Damn’d, because he understands no better than he does” (de Beer 1979: 601).  Molyneux’s point is well taken, and Locke acknowledges as much in his reply (de Beer 1979: 625). The source of the problem for the E1 account is that, with respect to the good (at least in the future), appearance does not always correspond with reality: it is possible for us to make mistakes about what is apt to produce the greatest pleasure and the least pain. Sometimes this is because we underestimate how pleasurable future pleasures will be (relative to present pleasures) or overestimate how painful present pains are (relative to future pains); and sometimes this is because we just make simple mistakes of fact, thinking, for example, that bloodletting will ease the pain of gout. As Molyneux sees it, we are not responsible for many of these mistakes, and yet it seems clear that we deserve (divine) punishment for making the wrong choices in our lives (e.g., when we choose the present pleasures of debauchery and villainy over the pleasures of heaven). Our sins, in other words, should be understood to proceed from the defective exercise of our wills, rather than from the defective state of our knowledge.
