Doing, Using, Utilitariansim

Using is a species of Doing, in which the object of Use serves the Doer as a means to an end.  So, Using entails Intention.  Now, according to Utilitarianism, the value of a consequential process is indifferent to the personal factors of its production, and, hence, to whether or not it is intentional, e. g. the value of even Liberty is contingent, according to Mill in On Liberty.  Thus, since 'use' and 'utility' are synonymous, Utilitarianism does not merely abstract from I, We, and Doing, in general--it is a misnomer.
