קהלת, פרק י״ב, פסוק י״ב

The human desire to gather and document all wisdom is an endless journey. Speaking with a fatherly tone, the wise man offers a gentle warning about the dangers of information overload and the attempt to absorb more than the human mind can carry. This paternal caution carries several layers of meaning. On a practical level, it serves as a direct warning against writing, buying, or reading an excessive number of books beyond the established texts of truth [אבן עזרא, ביאור שטיינזלץ]. Alternatively, this address is seen as an expression of deep affection, urging a person to be highly cautious in their actions and to distance themselves from sin even more than what is explicitly detailed in texts [מצודת דוד, תעלומות חכמה]. Another perspective views this as a call to strictly observe the Oral Torah and the teachings of the Sages, which are designed to protect biblical laws. According to this thought process, whenever a doubt arises regarding a rabbinic decree that involves a physical action, one should adopt a strict approach [רש״י, תורה תמימה, נחל אשכול, צאינה וראינה]. Additionally, this warning is linked to the concept of confusion, cautioning against bringing external texts outside the twenty-four books of the Bible into the home for regular study, as doing so only breeds mental chaos [תורה תמימה].

The natural question arises as to why all moral warnings and rabbinic decrees were not simply written down. The reality is that such a task is entirely impossible. If one were to attempt to detail and document every single thing a person must be careful to avoid, the writing process would never conclude [רש״י, מצודת דוד, תעלומות חכמה, צאינה וראינה]. Furthermore, dedicating deep research to fleeting and temporary matters only leads to the endless and ultimately useless production of literature [רלב״ג].

The physical and mental toll of this pursuit is profound, as the act of studying, deep thinking, or processing a jumble of words directly impacts the person [אבן עזרא, מצודת ציון, רלב״ג, ביאור שטיינזלץ]. The primary approach among commentators is that excessive reading and the attempt to absorb material beyond the natural limits of human memory and intellect will simply exhaust a person, draining their strength without yielding the desired results. However, this reality should never cause a person to despair or avoid learning altogether just because they cannot master everything [רש״י, צאינה וראינה]. In contrast to the idea of exhaustion, a different viewpoint finds a deeply positive meaning in this effort. Careful and meticulous Torah study grants a person profound satisfaction and a sense of fullness, much like the physical contentment experienced after eating a rich, satisfying meat meal [תורה תמימה]. When it comes to external books, the guidance remains clear that they are intended solely for casual, superficial reading, and should never be the subject of exhausting or permanent study [תורה תמימה, רלב״ג].
