If some entity pushes reality into some state -- across many contexts, not just by accident -- then you could say it prefers that state. Preferences are roughly equivalent to goals and values.

'''Preference''' is a normative side of [[optimization]]. Preference is roughly equivalent to goals and values, but the concept refers more to the sum total of all agent's goals and dispositions than to the individual components. For example, for an agent that runs a [[decision theory]] based on [[expected utility]] maximization, preference should specify both [[prior]] and [[utility function]].
 
 
Preference orderings that obey some [[rationality]] axioms can be represented by a [[utility function]].

Preference is a normative side of optimization. Preference is roughly equivalent to goals and values, but the concept refers more to the sum total of all agent's goals and dispositions than to the individual components. For example, for an agent that runs a decision theory based on expected utility maximization, preference should specify both prior and utility function.
