The inevitable reality of death forces a profound existential reckoning regarding the value of living a wise and just life. Death acts as the ultimate equalizer, coming for everyone without distinguishing between good and bad, or rich and poor [אבן עזרא, ביאור שטיינזלץ]. Confronting this shared human fate naturally sparks a difficult question: what is the purpose of investing so much effort into gaining wisdom if the final destination is exactly the same for everyone? [מצודת ציון, מצודת דוד].
This internal struggle operates on two distinct levels. On a practical and moral level, a person might wonder why they should work so hard to be righteous and wise when both the righteous and the wicked meet the exact same physical end [רש״י, צאינה וראינה]. On a deeper philosophical and spiritual level, this shared fate raises unsettling doubts about the survival of the soul after death. One might fear that the human soul is merely a biological, material force that perishes along with the body, sharing the destiny of the fool and the wicked whose souls are cut off. If there is indeed no eternal spiritual reality, then wisdom offers absolutely no advantage over foolishness [תעלומות חכמה].
Faced with these heavy thoughts, a conclusion is reached that something in this entire equation is empty and vain. The primary approach among commentators is that the hopeless thought itself—the idea that there is no difference between the wise person and the fool—is what is truly empty [מצודת דוד]. This pessimistic view is flawed for two main reasons. First, there is a vast difference in the legacy people leave behind. A wise and righteous person is remembered fondly, leaving a good name and honor for their children. In contrast, the wicked and foolish are remembered poorly, and whatever wealth or success they achieved is quickly lost and forgotten [רש״י, צאינה וראינה].
Second, the philosophical doubt about the afterlife is fundamentally incorrect because the soul does endure. Through good deeds and intellectual pursuit, the soul transforms from a mere physical capacity into an eternal spiritual essence. This is evidenced by the reality that wise scholars often maintain their mental clarity deep into old age thanks to their strong spiritual foundation, whereas ignorant individuals tend to lose their mental sharpness as their physical bodies weaken [תעלומות חכמה]. However, another perspective offers a different understanding of the conclusion. From this viewpoint, it is the pursuit of worldly wisdom itself that is ultimately empty, as all the earthly knowledge a person works for in this world cannot prevent physical death and the end of the body [אבן עזרא, ביאור שטיינזלץ].
