الأخلاق، الجزء V، القضية 5

An emotion towards a thing, which we conceive to be free, is greater than one towards what we conceive to be necessary (III. xlix.), and, consequently, still greater than one towards what we conceive as possible, or contingent (IV. xi.). But to conceive a thing as free can be nothing else than to conceive it simply, while we are in ignorance of the causes whereby it has been determined to action (II. xxxv. note); therefore, an emotion towards a thing which we conceive simply is, other conditions being equal, greater than one, which we feel towards what is necessary, possible, or contingent, and, consequently, it is the greatest of all.
