The divide between a person of deep insight and a foolish individual is not merely a matter of intelligence, but rather a profound difference in where they direct their lives and ambitions. Wisdom demands an active, internal pursuit, while foolishness easily settles in as a superficial habit and a constant companion. A discerning mind constantly and actively chases after knowledge [מצודת דוד, ביאור שטיינזלץ]. This pursuit is not about gathering superficial facts. Instead, it involves the ability to deduce complex ideas from one another to uncover the deeper reasons and secrets of wisdom, a process that requires intense contemplation and significant effort [מלבי״ם]. The knowledge being sought is the ultimate truth of the world and the ways of God [עמנואל הרומי], often understood as the knowledge of the holy [רלב״ג].
When studying prophetic texts, the insightful mind is never satisfied with the simple, literal narrative, recognizing it merely as metaphor. The true goal is to penetrate the hidden secrets within. The literal meaning is valued like silver, but the hidden secret is treasured like gold [עמנואל הרומי]. Furthermore, the pursuit of knowledge through Torah study is meant to bring joy to the heart and dispel sadness. Because deep learning requires a calm and settled mind, a person burdened by poverty and sorrow may find it difficult to achieve this level of understanding [אלשיך]. On a broader psychological level, a good and expansive heart is characterized by generosity and constant joy, standing in stark contrast to someone who deprives himself and severely restricts his resources [אמרי דעת].
Conversely, the behavior of fools is entirely different. A duality in the traditional text, where a word is written as face but read aloud as mouth [מנחת שי], reveals complementary psychological insights. Following the spoken reading of mouth, the lips of foolish people are accustomed to constantly speaking nonsense [ביאור שטיינזלץ, עמנואל הרומי]. This speech is not accidental; it flows directly from the foolishness that resides deep within their hearts, traveling outward to their lips [רלב״ג]. They make this foolishness their close friend and constant companion [מצודת דוד]. When applied to learning, fools merely graze on the outer shell and literal meaning of the texts, never making the effort to grasp the true inner intent [עמנואל הרומי]. Some interpret this grazing metaphorically as feeding on the forbidden delicacies of idolatry [אלשיך].
Looking at the written text as face uncovers a different psychological reality. A fool does not abandon wisdom out of absolute stupidity, but rather because he is driven by his physical desires. Consequently, he does not internalize the foolishness deep into his heart. Instead, he wears it outwardly on his face like a mask. He turns his face toward his desires, and foolishness stands before him like a flock of sheep, which he willingly shepherds and leads [מלבי״ם].
