Part V: Of the Power of the Intellect, Proposition XLII, Note

Baruch Spinoza

If men had not this hope and this fear, but believed that the mind perishes with the body, and that no hope of prolonged life remains for the wretches who are broken down with the burden of piety, they would return to their own inclinations, controlling everything in accordance with their lusts, and desiring to obey fortune rather than themselves. Such a course appears to me not less absurd than if a man, because he does not believe that he can by wholesome food sustain his body for ever, should wish to cram himself with poisons and deadly fare ; or if, because he sees that the mind is not eternal or immortal, he should prefer to be out of his mind altogether, and to live without the use of reason ; these ideas are so absurd as to be scarcely worth refuting. Prop. XLII. Blessedness is not the reward of virtue, but virtue itself ; neither do we rejoice therein, because we control our lusts, but, contrariwise, because we rejoice therein, we are able to control our lusts. Proof.—Blessedness consists in love towards God (V. xxxvi and note), which love springs from the third kind of knowledge (V. xxxii. Coroll.) ; therefore this love (III. iii. lix.) must be referred to the mind, in so far as the latter is active ; therefore (IV. Def. viii.) it is virtue itself. This was our first point. Again, in proportion as the mind rejoices more in this divine love or blessedness, so does it the more understand (V. xxxii.) ; that is (V. iii. Coroll.), so much the more power has it over the emotions, and (V. xxxviii.) so much the less is it subject to those emotions which are evil ; therefore, in proportion as the mind rejoices in this divine love or blessedness, so has it the power of controlling lusts. And, since human power in controlling the emotions consists solely in the understanding, it follows that no one rejoices in blessedness, because he has controlled his lusts, but, contrariwise, his power of controlling his lusts arises from this blessedness itself. Q.E.D. Note.—I have thus completed all I wished to set forth touching the mind's power over the emotions and the mind's freedom. Whence it appears, how potent is the wise man, and how much he surpasses the ignorant man, who is driven only by his lusts. For the ignorant man is not only distracted in various ways by external causes without ever gaining the true acquiescence of his spirit, but moreover lives, as it were unwitting of himself, and of God, and of things, and as soon as he ceases to suffer, ceases also to be. Whereas the wise man, in so far as he is regarded as such, is scarcely at all disturbed in spirit, but, being conscious of himself, and of God, and of things, by a certain eternal necessity, never ceases to be, but always possesses true acquiescence of his spirit. If the way which I have pointed out as leading to this result seems exceedingly hard, it may nevertheless be discovered. Needs must it be hard, since it is so seldom found. How would it be possible, if salvation were ready to our hand, and could without great labour be found, that it should be by almost all men neglected? But all things excellent are as difficult as they are rare.

Spinoza challenges the common view that virtue is a means to an end, instead proposing that virtue is the end itself. In the 17th century, many believed virtue was instrumental, a path to divine reward. Spinoza's radical stance flips this by suggesting true freedom and control come not from suppressing desires, but from the inherent joy found in understanding and living virtuously. This internal source of power confounds the causal link between virtue and reward, making them indistinguishable.
