“Man can be happy only through illusions, because truth destroys his happiness.”Giacomo Leopardi · Zibaldone · 1832 · p. 4174
Happiness lives not in reality but in the illusion that inflates it beyond measure.
Leopardi spots a psychological mechanism modern psychology has partly confirmed: hope and anticipation matter more than the pleasure attained, which always turns out smaller than imagined. That is why illusion, which inflates the object of desire beyond reality, is the condition of happiness, and exact knowledge dissolves it. Someone dreaming all winter about a vacation lives more happiness than in the days at the destination, where everything appears exactly as it is, measurable and finite.
If illusion sustains happiness, then maturity is not about giving it up, but about knowing how to use it. Leopardi points in an unexpected direction: do not choose between truth and dream, but keep a distance from both. Whoever knows their own illusions is no longer trapped by them, yet can still inhabit them. Think of someone planning a garden in February, knowing full well some plants will not take. The plan stays pleasurable precisely because they know where it ends. This raises the next question: what happens when someone else tells you, from outside, that your dream is unrealistic?
Why it matters Useful for understanding why ideals, projects, and dreams of the future sustain us more than their fulfillment does, and why they are worth keeping even when we know they are partly unrealistic.
