Jones' views on child psychopathy – as it relates to criminal deeds – were not to distinguish them from similar deeds committed by adults. Barring those aged 10 or younger (whom Jones said are "irrebuttably presumed not to be capable of criminal intent") and between 10 and 14 years old (where "there is only a rebuttable presumption that they are not so capable"), he believed that children are innocent only through a lack of comprehension of the wickedness of their deeds. To Jones, this was an insight into the psychopathy of adults: "An adult who does evil acts is either one who is still a child and cannot understand the evil nature of his acts, an adult who has become disinhibited, or one who has never become inhibited." {{quote box Jones' diagnoses relied on the
social contract theory, which he called "an aspect of the instinct for self-preservation." He believed all humans to be innately self-centred, inflicting their wills on the Universe as an "inner compulsion." Without the tacit arrangement of a social contract, humans would be uninhibited; with it, they recognise the mutual benefits of society and are inhibited by virtue. ==Personal life==
