Introduction
Chapter 18 of Mishlei opens with two verses that deal with two very different spiritual afflictions: the first is the attempt to separate oneself entirely from physical desire, and the second is the person who has no interest in hearing or knowing the truth, but seeks only to express what is in his heart. We will proceed verse by verse, citing the explanations of the Malbim, Rabbeinu Yonah, and the Vilna Gaon, and draw practical lessons for life from them.
Verse 1: "He who separates seeks desire" - The Malbim's Novel Explanation
לְתַאֲוָה יְבַקֵּשׁ נִפְרָד בְּכָל תּוּשִׁיָּה יִתְגַּלָּע׃ - He who separates seeks desire; against all sound wisdom he will break out.
The Malbim notes a precision in the verse's wording: it does not say "for desire he seeks and separates," but rather "has separated" (nifrad) - in the past tense. This refers to someone who has already been separated from bodily desire, yet now seeks it out. Who is this? For example, an elderly or sick person who has already parted from desire due to his age and frailty, yet searches for schemes to rekindle desire - using herbs, potions, and remedies to artificially restore it. Carnal matters no longer stir him naturally, so he resorts to stimulants to drag himself back into worldly lusts.
Here, the Malbim also explains tushiyah differently than usual: not from the root of wisdom, but from tash - weakness and depletion of strength. This person exhausts and weakens his body in every way. A person's vitality is his strength, as Scripture states, "Do not give your strength to women" - in its literal sense, that he expends his physical vitality. If his body is already worn out and frail, and he artificially manufactures desires, he ends up debilitating himself far more than before.
Second Explanation: Extreme Asceticism Intensifies Desire
The Malbim offers another interpretation, which is equally profound and true: one who separates completely from desire, like monks who retreated into deserts far from human civilization, finds that their lusts flare up even more intensely, precisely because they crave desire when it is unavailable to them. "And against all sound counsel he breaks out" - with every existing reality (yeish) that presents itself before them, desire erupts with even greater fury.
How true this is. It is impossible to suppress desire completely. The Torah teaches the proper way of life for a person: to marry a wife. There is no demand for a person to remain celibate; on the contrary, one should marry and channel his urges peacefully and properly, as holy books explain. The Holy One, blessed be He, created needs and drives within human beings, and a person must channel and express them in a path of holiness.
The Parable of the Horse and the Rider
This can be illustrated by the parable of a horse and rider. The horse represents the body, the animalistic element within man, which seeks pleasure and desires. The rider represents the soul, the spiritual dimension, which seeks spirituality: ice cream cannot satisfy the soul, but a heartfelt prayer, deep study, or a mitzvah fulfilled with beauty fills it completely. An act of kindness done for a fellow Jew grants a sense of fulfillment that lingers long afterward. That is spiritual satisfaction.
Christianity came along and declared: There is indeed a conflict here; the soul pulls in one direction and the horse pulls in another. The solution? Kill the horse. Ascetic celibacy. Do not marry, do not indulge, do not listen to the body. And then human nature takes its course, as Rav Lasry famously describes: a monastery on one side, a convent on the other, and an orphanage in between - with no one knowing where the children came from. A human being cannot genuinely live in total celibacy; realistically, it is simply impossible. Furthermore, the Torah permitted the eishes yefas to'ar (the captive woman of war) on the grounds that "it is better for him to take her permissibly than forbiddenly" - the Torah acknowledges that without a permissible outlet, he would very likely take her through prohibition.
If the Christians found a solution in killing the horse, Judaism found a different solution: giving the rider a pair of reins. You need the horse, and without it, one cannot serve the Creator - after all, one serves Hashem with the energy derived from eating, drinking, and sleeping. But you must hold reins. For its part, the horse would gladly sleep until noon and eat without end; it has no problem doing so, it is a horse. That is why you were given reins: at this hour I get up, now there is Torah study, now there is prayer. Sleep - but know when to stop. Eat - but know when to stop. And so it is with all other physical desires.
This is why the Gemara emphasizes: "Whatever the Merciful One forbade us, He permitted to us something comparable" - for everything the Holy One, blessed be He, forbade us, He permitted us something similar. He forbade us blood - He permitted us liver, which is full of blood. He forbade us pig - He permitted us the shibuta fish, which has the flavor of pork. He forbade a married woman - He permitted a divorcee, who was once a married woman. The Gemara is telling us: for everything forbidden, there is a counterpart that is permitted. The Torah does not tell you, "Abstain entirely," but rather, "Apply the brakes." Partake - but within boundaries, not without limits.
The Compressed Spring
A person says to himself: No, it is impossible; if I begin with this, I will be dragged down. The best thing is to abstain completely - and so he withholds himself from every desire, even through permissible means. Regarding this, the verse states: "He who separates himself seeks desire" - one who seeks to separate entirely from all worldly desire in order to become an exalted saint will ultimately find that "he breaks out against all sound counsel"; he will seek out his desire and expend it on anything at all. By way of allusion, even the most foul and base matters, to which a person would not naturally be drawn, will no longer be off-limits to him. Why? Like a spring: the harder you compress it, the more forcefully it recoils.
This phenomenon is well known and sometimes seen among ba'alei teshuvah. When they lack proper guidance, they do not follow the correct path of moving step by step, of the gradual ascent of "Who may ascend the mountain of Hashem?" Instead, they try to go from wicked today to righteous tomorrow. The Rambam describes how a person was previously detestable and shunned, praying only to have his prayer torn up before him, and now he is beloved, close, righteous, and pious before the Omnipresent - and this person wants to leap there overnight. Yesterday he put on tzitzit after a lecture, today he is already wearing a hat and jacket, changing everything in one fell swoop. A month later, you find him not merely back where he started, but in a worse state. What happened? You suffocated and suppressed yourself again and again - and that can cause far greater harm.
The Testimony of the Chazon Ish
The Chazon Ish recounted about himself that he was once studying and reached a state of extreme weakness and severe headaches. As is well known, he studied with immense diligence (hasmadah) for uninterrupted hours, and it was written of him that all the lofty levels he attained were due to his great continuous diligence. On that occasion, he was delving deeply into a Talmudic topic and felt that he could no longer go on, that his body was unable to bear it. Yet he told himself: No, this is the counsel of the yetzer hara - and he pushed himself even harder. Afterwards, a blood vessel apparently ruptured; he went to a doctor, and he was forbidden to study in depth (be-iyun) for an entire year. Regarding this, he said: That illusory "self-sacrifice" inspired by the yetzer hara cost me a whole year. It was a year in which he was permitted to study only lightly and broadly (be-beki'ut), and for the Chazon Ish, that was like telling a starving man to eat crumb by crumb, without seasoning. A terrible punishment.
From this we learn that when it seems to a person that he must go to the furthest extreme and that this is the only way, he must ask a Rav, consult a Torah scholar, and not act on his own. It is very possible that what you are doing will harm you, bringing you to a difficult situation from which it will be far harder to emerge. This is especially true for one who became observant and later slipped back - it is exceptionally difficult for him to return again, because he feels, "I was already there." It is just like how it is hardest to inspire a religious person to do teshuvah: "After all, I pray three times a day, I even set aside time for Torah study once a week, there is a radio program I listen to" - he feels he is perfectly fine, so regarding what should he repent? The same is true for one who studied and then turned away: for him, it is no longer a revelation. And what caused this? The fact that his initial approach was flawed, driven by excessive extremism.
Therefore, anyone becoming observant, or anyone wishing to adopt some pious practice (chassidut), must first consult a Torah scholar to see whether it suits him, whether it matches his level, or if he has skipped several rungs and ought rather to advance step by step. Countless people would come to the leading Torah sages - to Rav Chaim Kanievsky, Rav Ovadia Yosef, and many others - and say: "I have become observant; I want to shut everything down and sit and learn in kollel full-time." And the sages would not agree under any circumstances. They would ask him: "What do you do currently?" "I attend a shiur." "Continue attending your shiur, add another hour, study half a day in kollel - and that is all." For a person who has never studied full-time, and now seeks to overturn his entire reality, places himself in severe strain and turns his home into a pressure cooker: until now you brought home twelve thousand shekels, and now you want to sit and learn on what? On what a kollel stipend pays? Do not be impressed by the figures displayed in political campaigns claiming that a kollel student receives thousands of shekels from the state - that is pure fiction, and much has been written about it. A friend jokingly remarked that he is still looking for those who promised him that money! In short, progress must be measured and gradual.
This is the message King Solomon teaches us: one must proceed gradually, in stages. Do not imagine that if you have severed yourself from worldly desire, you have eliminated that desire - on the contrary, "against all sound wisdom he will break out"; through such extreme suppression, you will only arrive at far more severe and dangerous states.
Verse 2: The Fool Does Not Want to Understand, Only to Speak
לֹא יַחְפֹּץ כְּסִיל בִּתְבוּנָה כִּי אִם בְּהִתְגַּלּוֹת לִבּוֹ׃ - A fool does not desire understanding, but only to express what is in his heart.
Rabbeinu Yonah explains: When the kesil (fool) speaks, he does not want to know the truth, but merely to reveal his heart. If a question is asked and everyone wants to answer, there is the person who is subsequently interested in discovering what the true answer is, and there is the one who, once he has said his piece, no longer cares what you have to say, because all that mattered to him was making his voice heard. How does Shlomo define him? A kesil. The wise person says: "Well, let us listen; I want to hear what you have to say." The kesil only wants to blurt out what is in his mouth: "No, I know, leave it, I am familiar with that, I have studied it." Such a person will remain a kesil forever. But one who says, "Do you have something to say? By all means, I want to hear it; perhaps you will teach me something new" - even if he has already heard it once, hearing it again brings renewed inspiration and additional details. The kesil does not desire understanding, meaning he does not want to contemplate. Sometimes he seemingly listens to you: "Yes, yes, I heard you; now hear what I have to say" - but did you contemplate what was said? Had he wanted to contemplate, he would have deliberated over the words and grasped the wisdom within them. Rather, "only in revealing his heart" - to reveal what is on his heart, and nothing more.
The Vilna Gaon adds: The kesil, even when he comes to the beit midrash, does not come to learn Torah, since in truth he does not desire understanding. He comes to display his wisdom. When he speaks to someone in learning, his intention is to show everyone how much he knows, how wise he is, and that he knows things others do not know.
A Question That Does Not Seek an Answer
From this emerges a practical guideline: When a person only wants a platform to vent what he has inside, there is no point in answering him, as he is not looking for an answer at all. You let him say his piece - and you have bought quiet. He has vented his feelings, as it says, "A fool vents all his anger," and you move on. If he were truly interested, he would say: "Wait, I want to hear; explain it to me." But often you begin to explain, and he continues to argue, repeating his words. Try to understand what I answered you - perhaps the answer is already within my words. Yet the truth is that he is not interested in an answer, because the moment you have an answer, you have taken away his question. Until now he felt comfortable with his objection, and you are trying to take it away from him - especially when the question legitimizes his actions.
"Where was the Master of the Universe during the Holocaust?" and all sorts of questions of this kind. In most cases, there is no point in answering such questioners. Do you want to test whether he is truly seeking an answer? Say to him: "Do you really want an answer? Take my phone number, call me at such-and-such a time, and we will sit and talk." Do not worry; he will not call, nor will he even take the number. He does not want an answer; he wants to ask a question in order to feel comfortable with what he is doing. Do not ask me why I do not observe mitzvot - I have a question, and if you resolve it, you will compel me to observe mitzvot, so from the outset I do not accept your response. The same applies to "Why do yeshivah students not serve in the army?" - tell him: "Do you really want to know? I cannot answer standing on one foot; call me at nine o'clock this evening, and I will even call you back, just give me a missed call." Do not worry, you do not need to clear that hour; he will not call. Most people who pose such questions do not come to ask, but to provoke: "Who are you to feel superior to me?" These are rhetorical questions, not the questions of a seeker of truth. This does not refer to someone sitting in a shiur asking a genuine question, but specifically to this type of question.
The Wicked Son Who Asked and Left
It is told of one of the great Torah leaders who was walking with a group of disciples, when suddenly a scoffer arrived with a group of friends and asked him in front of everyone: "I have a question on the Pesach Haggadah. It says that the wicked son asks, 'What is this service to you?' and you blunt his teeth and tell him, 'Had he been there, he would not have been redeemed' - why does it say 'Had he been there'? After all, you are speaking directly to him; it should have said, 'Had you been there'!" He chuckled with his friends and walked off. The Rav said to his students: "This wicked person answered his own question by his very action. The answer is that the rasha (wicked person) never waits to hear an answer; he asks his question and walks away. And to whom must one answer? To the righteous who remained here to listen, so that the question does not seep into them. Therefore, we say to them: Know that had he - that wicked person who has already managed to walk away - been there, he would not have been redeemed."
The Difference Between a Kesil and an Evil
The Malbim, as is his way throughout the entire book, distinguishes between a kesil and an evil. An evil derives from the word ulai (perhaps) - this is the skeptical type, who asks about everything: "Who said so? What is the proof? Who knows that it is so?" The kesil, on the other hand, knows everything; he is an immense expert - like Esav. He knows everything, but there is a disconnect between his knowledge and its application: he knows, yet follows the desires of his heart.
Therefore, the verse is precise in not saying, "An evil does not desire understanding," because the evil actually desires understanding: he asks, "Who said so?", but if you prove it to him, he will be glad. He is genuinely skeptical; he lacks proofs, and had he been able to avoid doubting, it would have been better for him. But the kesil knows everything. You come to explain it to him - he knows your words well, and will even provide further citations showing how right you are. His problem is not one of knowledge, but of desires that pull him in another direction. Therefore, "A fool does not desire understanding" at all: "Do not come and explain to me how bad my actions are; do not show me studies that smoking is harmful." The kesil is a person who knows yet does not act, and does not wish to hear.
"Only in revealing his heart" - for him, the heart is the source of desires, and he wants them to be revealed, which means putting all his desires into action. And why would he need you preaching to him? As someone once said: Conscience has never stopped a person from doing anything; it merely prevented him from enjoying what he does. He will continue his actions, and pangs of conscience will only rob him of the taste of sin, without actually preventing it. Thus, the rebuke you give him ultimately does nothing but spoil his pleasure - and therefore he does not desire understanding, but rather to do whatever enters his heart, which is the lust of his heart.
In summary:
These two verses teach two warnings. The first: "One who separates himself seeks desire" - whoever seeks to detach himself completely from physical desire will ultimately find that it erupts in everything he does, like a compressed spring. The way of the Torah is not to kill the horse, but to hold the reins: to partake in what is permitted, with boundaries, gradually, and with the guidance of a wise teacher. The second: "A fool does not desire understanding" - the fool does not seek truth, but merely a platform to voice his own opinions and vent his heart's desires; therefore, there is no benefit in the answers you give him. The wise man, by contrast, always seeks to listen, reflect, and advance step by step.
