 A subsequent book, "The Proactionary Imperative" by Fuller and Lipinska attempts to make the proactionary principle fundamental to transhumanism as a world-view, stressing the principle's interpretation of risk as an opportunity rather than a threat.In theory, sufficient study of the variables of any proposed course of action may yield acceptable levels of predictability.In this regard the proactionary principle can be looked upon as the philosophical formulation of the accepted mathematical principles of "extrapolation" and the logical principles of "induction".
