Aristotle uses a powerful botanical metaphor to describe the process of gaining knowledge. The "roots"—the initial struggle, the discipline of study, the frustration of not understanding—are "bitter." This stage requires hard work, patience, and often involves failure.

But if you persevere through this difficult phase, you eventually produce "fruit"—the wisdom, skill, and understanding that come from mastery. This fruit is "sweet," representing the joy, freedom, and opportunities that a good education provides. The reward is proportional to the effort invested in the beginning.

This quote provides motivation during the challenging phases of learning. It reassures us that the initial struggle is normal and necessary, and it promises a sweet reward for those who have the perseverance to see the process through.
