The Torah treats idolatry and pagan practices with extreme severity, condemning them repeatedly throughout the Tanach. In Moshe’s last address, he issues the same instruction to be weary of these foreign practices:
כִּי אַתָּה בָּא אֶל־הָאָרֶץ אֲשֶׁר־ה אֱלֹהֶיךָ נֹתֵן לָךְ לֹא־תִלְמַד לַעֲשׂוֹת כְּתוֹעֲבֹת הַגּוֹיִם הָהֵם׃ לֹא־יִמָּצֵא בְךָ מַעֲבִיר בְּנוֹ־וּבִתּוֹ בָּאֵשׁ קֹסֵם קְסָמִים מְעוֹנֵן וּמְנַחֵשׁ וּמְכַשֵּׁף׃ וְחֹבֵר חָבֶר וְשֹׁאֵל אוֹב וְיִדְּעֹנִי וְדֹרֵשׁ אֶל־הַמֵּתִים׃כִּי־תוֹעֲבַת ה כָּל־עֹשֵׂה אֵלֶּה וּבִגְלַל הַתּוֹעֵבֹת הָאֵלֶּה ה אֱלֹהֶיךָ מוֹרִישׁ אוֹתָם מִפָּנֶיךָ׃ תָּמִים תִּהְיֶה עִם ה אֱלֹהֶיךָ׃ – When you enter the land that Hashem is giving you, you shall not learn to imitate the abominable practices of those nations. Let no one be found among you who sends his son or daughter to the fire, or who is an augur, a soothsayer, a diviner, a sorcerer, one who casts spells, or one who consults ghosts or familiar spirits, or one who inquires of the dead. For anyone who does such things is abhorrent to Hashem, and it is because of these abominable things that the Hashem is dispossessing them before you. You must be perfectly wholehearted with Hashem. (18:9-13)
While extremely difficult to reconcile with a modern understanding of how the world works, it would be obtuse to deny that a sizable portion of Jewish tradition incorporates magic and superstition as having some actual basis and realism – the book of Shmuel tells of an incident where years after the settlement of the Land of Israel, a Philistine army threatened the young state, and King Saul sought a witch out to consult with the ghostly spirit of the dead prophet Shmuel.
Be that as it may, there is a divergent rationalist school of thought more aligned with a modern understanding of the world, notably the Rambam, that does not treat these as genuine, but still equally forbidden.
Real or not, the Torah is explicit that seeking out future knowledge is taboo and, therefore, off-limits. Instead, we should embrace the future straightforwardly as it comes – תָּמִים תִּהְיֶה עִם ה אֱלֹהֶיךָ.
What’s so wrong about wanting to know the future?
R’ Yakov Hillel explains that someone seeking future knowledge yearns to eliminate doubt and uncertainty, which is antithetical to the human condition.
Humans hate uncertainty. It is stressful and makes us worry. Every day, we navigate over the shaky, uncertain, and constantly changing landscape of probabilities that lie before us.
We have natural pattern recognition abilities, which is why humans are prone to believe in magic and superstition. Doubt and uncertainty are fundamental and intrinsic to the human condition – we aren’t computer programs. Uncertainty is central to the Jewish conception of prophecy; counterintuitively, a prophet’s job is not to foretell an inevitable future – instead, their job is to warn people away from the path they are on. A prophet whose warning comes true has failed! The future is not set, which is also a central theme of the High Holy Days.
This is also the theme of Isaiah critique that is read before Tisha b’Av, where Isaiah calls his community to task, people who, instead of doing the work to alleviate poverty and suffering, and be good and kind to each other, would rather just slaughter a goat or two:
לָמָּה-לִּי רֹב-זִבְחֵיכֶם יֹאמַר ה שָׂבַעְתִּי עֹלוֹת אֵילִים וְחֵלֶב מְרִיאִים וְדַם פָּרִים וּכְבָשִׂים וְעַתּוּדִים לֹא חָפָצְתִּי. כִּי תָבֹאוּ לֵרָאוֹת פָּנָי מִי-בִקֵּשׁ זֹאת מִיֶּדְכֶם רְמֹס חֲצֵרָי. לֹא תוֹסִיפוּ הָבִיא מִנְחַת-שָׁוְא קְטֹרֶת תּוֹעֵבָה הִיא לִי חֹדֶשׁ וְשַׁבָּת קְרֹא מִקְרָא לֹא-אוּכַל אָוֶן וַעֲצָרָה. חָדְשֵׁיכֶם וּמוֹעֲדֵיכֶם שָׂנְאָה נַפְשִׁי הָיוּ עָלַי לָטֹרַח נִלְאֵיתִי נְשֹׂא. וּבְפָרִשְׂכֶם כַּפֵּיכֶם אַעְלִים עֵינַי מִכֶּם גַּם כִּי-תַרְבּוּ תְפִלָּה אֵינֶנִּי שֹׁמֵעַ יְדֵיכֶם דָּמִים מָלֵאוּ. רַחֲצוּ הִזַּכּוּ הָסִירוּ רֹעַ מַעַלְלֵיכֶם מִנֶּגֶד עֵינָי חִדְלוּ הָרֵעַ. לִמְדוּ הֵיטֵב דִּרְשׁוּ מִשְׁפָּט אַשְּׁרוּ חָמוֹץ שִׁפְטוּ יָתוֹם רִיבוּ אַלְמָנָה – “What makes you think I want all your sacrifices?”, says Hashem. “I am stuffed with burnt offerings and ram sacrifices and cattle fats. I don’t need the blood of bulls, lambs and goats. When you come to worship me, who asked you to parade through my courts with all your ceremony? Stop bringing me your meaningless gifts; the incense of your offerings disgusts me!
“Your celebrations of Rosh Chodesh and Shabbos and your fast days, are all sinful and false. I want no more of your pious meetings! I hate your new moon celebrations and your annual festivals. They are a burden to me. I cannot stand them! When you raise your hands in prayer, I will not look. Though you might offer many prayers, I will not listen, because your hands are covered with the blood of innocents!
“Wash yourselves and become clean! Get your sins out of my sight. Give up your evil ways; learn to do good. Seek justice! Help the oppressed and vulnerable! Defend the cause of orphans! Fight for the rights of widows!” – (1:10-17)
It is normal to be scared of the future, but that fear can paralyze us from doing the work we need to do. By holding on to what we need from the future, we use shortcuts to hack the outcome.
Instead, the Torah advises us to be wholesome, to embrace the struggle the uncertainty and fear of the future straightforwardly as it comes – תָּמִים תִּהְיֶה עִם ה אֱלֹהֶיךָ.
Maybe there are religious hacks. But R’ Yitzchak Berkowitz notes that people who are wholesome and straightforward understand that shortcuts are no substitute for the real deal.
The human enterprise is trial and error, courage, and risk. R’ Shlomo Farhi explains that shortcuts are pitfalls – the bad and wrong ways to do things. We need to prepare for the future properly you can’t hack your way into being a decent human – you can’t ask for forgiveness before making amends; you can’t lose weight sorting out your diet; you can’t retire without saving.
When we are afraid of the future, there is something we want to avoid. Instead of avoiding the pain, confront it, put in the work, and take decisive action.
