Stuart Mill emphasized the value of higher pleasures over simple satisfaction, suggesting that it is preferable to experience dissatisfaction from intellectual or moral pursuits rather than be content with base or trivial pleasures. According to him, individuals who are unaware of the deeper happiness they might pursue tend to prefer immediate, superficial pleasures, but this is because they are limited by their own perspective.
Mill's quote highlights that those who are satisfied with less may not understand the true worth of higher pleasures, which can lead to misguided opinions. It encourages valuing ongoing intellectual and moral development over complacency, recognizing that true satisfaction often comes from challenging and evolving oneself.
