InJudaism,yetzer hara (Hebrew:יֵצֶר הַרַע,romanized: yēṣer haraʿ) is a term for humankind's congenital inclination to doevil. The term is drawn from the phrase "the inclination of the heart of man is evil" (Biblical Hebrew:יֵצֶר לֵב הָאָדָם רַע,romanized: yêṣer lêḇ hā-ʾāḏām raʿ), which occurs twice at the beginning of theTorah (Genesis 6:5 and Genesis 8:21).
The Hebrew wordyetzer having appeared twice in Genesis occurs again at the end of the Torah: "I knew their devisings that they do".[1] Thus from beginning to end the heart'syetzer (plan) is continually bent on evil. However, the Torah which began with blessing[2] anticipates future blessing[3] which will come as a result of God circumcising the heart in the latter days.[4]
In traditional Judaism,yetzer hara is not a demonic force; despite this,Samael is considered the source of theyetzer hara, through man's misuse of things the physical body needs to survive. Thus, the need for food becomes gluttony due to theyetzer hara. The need for procreation becomes promiscuity, and so on.
The Jewish concept of theyetzer hara is similar to the Christian notion of "fallenness" or a corrupted human nature, known in theAugustinian tradition asconcupiscence, humanity's alienation from God and theimage of God in oneself and others, resulting in spiritual ignorance and rebellion, the progressive loss of divine likeness, and a tendency to entertain evil thoughts and commit evil acts. However, the genesis of concupiscence isoriginal orancestral sin, whereas theyetzer hara is a natural aspect of God's creation.
According to the Talmudic tractateAvot de-Rabbi Natan, a boy's evil inclination is greater than his good inclination until he turns 13 (bar mitzvah), at which point the good inclination is "born" and able to control his behavior.[5] Moreover, the rabbis have stated: "The greater the man, the greater his [evil] inclination."[6]
The underlying principle in Jewish thought states that each person—Jew and gentile alike—is born with both a good and an evil inclination.[7] Possessing an evil inclination is considered neither bad nor abnormal. The problem, however, arises when one makes a willful choice to "cross over the line," and seeks to gratify their evil inclination, based on the prototypical models of right and wrong in the Hebrew Bible.[8] This notion is succinctly worded in theBabylonian Talmud: "Everything is determined by heaven, except one's fear of heaven,"[9] meaning, everything in a person's life is predetermined by God—except that person's choice to be either righteous or wicked, which is left to theirfree will.
The Bible states that every person on some occasion succumbs to their evil inclination: "For there is not a righteous man upon earth, that doeth good, and sinneth not."[10] TheTalmud speaks of the difficulty in overcoming the evil inclination: "To what is it like, the evil inclination in man? It is like a father who takes his small son, bathes him, douses him with perfume, combs his hair, dresses him up in his finest accoutrements, feeds him, gives him drink, places a bag of money around his neck, and then goes off and puts his son at the front door of a brothel. What can the boy do that he not sin?"[11] In recognition of this difficulty, repentance (and in some cases, affliction) is said to atone for most sins, while the preponderance of good works keeps one within the general class of good people.[12]
Maimonides gave instructions for how to view the evil inclination and ensuing hardships on that account:
...Therefore, let a man prepare his own mind and request from God that anything that should ever happen to him in this world, whether of the things that are by God's providence good, or of the things that are by Him evil, that the reason [for their occurrence] is so that he might attain true happiness. Now this was stated with regard to the Good Inclination [in man] and with regard to [his] Evil Inclination, that is to say, that he might lay to his heart the love of God and his [continued] faith in Him, even at an hour of rebellion or of wrath or of displeasure, seeing that all of this revolves around [man's] evil inclination, just as they have said: 'In all your ways acknowledge Him',[13] [meaning], even in a matter involving transgression.[14]
Moshe Chaim Luzzatto wrote inDerech Hashem that "Man is the creature created for the purpose of being drawn close to God. He is placed between perfection and deficiency, with the power to earn perfection. Man must earn this perfection, however, through his own free will... Man's inclinations are therefore balanced between good (Yetzer HaTov) and evil (Yetzer HaRa), and he is not compelled toward either of them. He has the power of choice and is able to choose either side knowingly and willingly".[15]
While God has created mankind with both good and evil inclinations, the two powers or tendencies that pull one in opposite directions, God commands each person to choose the good and right path over the evil. In the narrative ofCain and Abel, God tells Cain: "Isn't it true that if you do good, you shall be forgiven? However, if you will not do good, it is because sin crouches at the entrance [of your heart], and to you shall be its longing, although you have the ability to subdue it."[16] Medieval commentatorRashi explains: "and to you shall be its longing," meaning, the longing of sin—i.e., the evil inclination—which constantly longs and lusts to cause one to stumble, "although you have the ability to subdue it," meaning, if a person wishes, they will overpower it.[17]
The implication is that each person is capable of overcoming sin if they really wish to do so. This may or may not be difficult, and may require some reconditioning, but it is still possible.
Although there are many vices, the Sages of Israel have said that most people are drawn to "stealing" what does not belong to them (גזל), while fewer people are inclined to "uncover the nakedness" of others (גלוי עריות), a euphemism for lechery.[18] Onlust,Shalom Shabazi (1619 –c. 1720) calls it "a phenomenon of the soul," and lays out ways in which a person tempted by lust can overcome the urge, without being swept into its clutches.[19][a]
Inrabbinic literature, theyetzer hara is seen as a fundamental force driving humans toward sin, particularlyidolatry. This inclination is viewed as an inherent aspect of human nature, leading people away from divine worship and towards the veneration of false gods.
According to a well-known legend from theTalmud, the rabbis at the beginning of theSecond Temple period recognized the destructive power of theyetzer hara for idolatry and decided to eliminate it. They engaged in intense prayer and fasting, asking God to remove this inclination from the world. In response, God granted their request, and the rabbis were able to capture the evil inclination for idolatry.
However, the aftermath of this act showed the complexity of their decision; the absence of theyetzer hara also diminished the human drive for other essential aspects of life, such asprocreation (see below). How exactly this reality shift played out and continues to be manifest, has been discussed by many scholars including suchthinkers as RabbiAvraham Yitzchak Kook, RabbiZadok HaKohen ofLublin, and others.[21]
Rabbinic sources also describe theyetzer hara (when properly channeled) as necessary for the continuation of society, as sexual lust motivates the formation of families, and greed motivates work:
Rabbi Nahman bar Samuel bar Nachman said in the name of RabbiSamuel bar Nachman: [...] "And behold it was very good" (Genesis 1:31)—this refers to theyetzer hara. But is theyetzer hara indeed very good?!—Were it not for theyetzer hara, a man would not build a home, or marry a woman, or have children, or engage in business.[22]
TheMishnah interprets the Biblical command to love God "with all your heart"[23] to mean "with your two inclinations—good inclination and evil inclination".[24] The latter half of this interpretation has been interpreted in various ways. According to some, it indicates that physical pleasures such as eating and drinking can be a form of service to God, if one's intention is to thereby strengthen the body in order to better serve God.[25]
Theyetzer hara is also seen positively in that its existence allows for free will, which in turn allows for reward for those who choose good deeds.[26]
Although certain ancient groups of Jews appear to have believed in the existence of supernatural evil, in particularfallen angels (as in theDead Sea scrolls),[27][28][29] theyetzer hara in non-apocryphal sources is presented as a personification of evil distinct from the supernaturalDevil of traditional Christianity and Islam. This tendency to demythologizeSatan is found in theBabylonian Talmud[30] and other rabbinical works, e.g.: "Resh Laqish said: Satan, the evil inclination, and the Angel of Death are all one."[31] Notably, however, this and other passages of the Talmud do not deny the external existence of Satan, but create a synthesis between external and internal forces of evil.[32][33][34] Similar tendencies can also be found in some Enlightenment Christian writers, such as in the religious writings ofIsaac Newton.[35][clarification needed]
Many of the enactments made by the rabbis throughout the centuries are actual "safeguards" to distance a person from their natural inclination and make it harder for them to sin. David's prohibition againstyichud (the decree which forbids a man to be secluded in a room with a woman unrelated to him),[36] and the rules outlining the conduct of Jews when entering apublic bath house, are a just a few examples. Still, in the case of abeautiful captive woman during the time of war, the Torah allows a Jewish soldier to make contact with such a woman(Deuteronomy 21:10–14). The rabbis call it a concession to man's evil inclination.[37] RabbiAbraham Isaac Kook explains that the allowance of a 'beautiful captive woman' makes use of the psychological principle of "one that has bread in his basket," (aeuphemism for one who is married and is able to engage in sexual relations with his wife at his own discretion) according to which the mere knowledge that something is permitted enables the soldier to exercise restraint and to overcome his inclination.[38]
