'''Utils''' are the unit of measurement for [[utility function|utility]], or the degree to which [[preference]]s are satisfied. They are a purely abstract unit; there is no standard definition of how much goodness constitutes one util. Unlike dollars, utilons are assumed to always be equally valuable; where there are diminishing returns, that is represented in the conversion from states into utility, not in a change in the marginal value of one util. Utils are not to be confused with [[hedon]]s, units of subjective pleasure, or [[fuzzies]], the warm feelings associated with the belief that one has accomplished good.

'''Utility''' is the amount by which preferences are satisfied. An abstract measure of utility is  called a '''Util''', or '''utilon'''. It is an arbitrary quantity, but can be consistently assigned once a set of [['''Utility Functions''']] are defined. All utils are equal; any diminishing returns or other factors are accounted for when utils are measured. Utils are not to be confused with hedons, units of subjective pleasure, or fuzzies, the warm feelings associated with the belief that one has accomplished good.

Utility is the amount by which preferences are satisfied. An abstract measure of utility is called a Util, or utilon. It is an arbitrary quantity, but can be consistently assigned once a set of '''Utility Functions''' are defined. All utils are equal; any diminishing returns or other factors are accounted for when utils are measured. Utils are not to be confused with hedons, units of subjective pleasure, or fuzzies, the warm feelings associated with the belief that one has accomplished good.

Utilitarianism is the philosophy that advocates whatever action produces the greatest amount of utility is the moral action.
