Kohelet Rabbah, a collection of rabbinic interpretations on the Book of Ecclesiastes, dives into this very idea, using the verse "The wise man, his eyes are in his head, but the fool walks in darkness" (Ecclesiastes 2:14) as its starting point. But who are these wise and foolish figures?
The text explains that "the wise man, his eyes are in his head" refers to a Torah scholar, someone deeply versed in their studies. They've put in the time, the effort, the dedication to truly understand the teachings. But "the fool who walks in darkness"? That's someone who studied Torah, yes, but didn't invest the necessary time and energy to achieve that same level of expertise.
Now, here's where it gets interesting. Both are called "rabbi." Both might even wrap themselves in a tallit, a prayer shawl. (It was apparently common for Torah scholars back then to spend much of their day enveloped in its fringes). So, what's the difference? If they both look the part, why does one walk in darkness?
The text continues with a powerful question: "Why did I become wiser? Why did I give my life for my Torah?" It's a cry of frustration! If the wise and the foolish seem so similar on the surface, what was the point of all the hard work?
The answer lies in what happens "tomorrow," when they enter the assembly. They are asked questions. One responds with insight and wisdom, drawing upon their deep understanding. The other? Silent. Unable to answer. As it says, "How can the wise man die like the fool?" They may both die, but their legacies are vastly different.
Rabbi Ḥiyya bar Neḥemya offers another crucial perspective. He says that if a student isn't required to cite a lesson in the name of their teacher, then the teacher’s Torah will be forgotten. It is the student who will perpetuate the teacher's teachings. So, how can the teacher do anything but devote themselves to their student?
It’s a poignant reminder that wisdom isn't just about accumulating knowledge, but about sharing it, passing it on, and ensuring its survival. It's about investing in the future, in the next generation of learners. It's not enough to be wise; we must also cultivate wisdom in others. Because ultimately, our legacy isn't just what we know, but what we leave behind. What we inspire in others.
