Parry (1987), p. 5: "The illegalists in this study,...As anarchist individualists, they came from a milieu whose most important theoretical inspiration was undoubtedly Max Stirner—whose work The Ego and Its Own remains the most powerful negation of the State, and affirmation of the individual, to date."

Parry (1987), p. 15: "A new generation of anarchists, spurred on by the individualist' ideas of Max Stirner, were to take as their point of departure exactly what Jean Grave objected to, that the rebel who secretly stole was no more than an ordinary thief. The developing theory of 'illegalism' had no moral basis recognizing only the reality of might in place of a theory of 'right'. Illegal acts were to be done simply to satisfy one's desires, not for the greater glory of some external 'ideal'. The illegalists were to make a theory of theft without the embarrassment of theoretical justifications." Parry, Richard (1987). The Bonnot Gang. London: Rebel Press. ISBN0-946061-04-1.
