The Rationale For The Dietary Laws

The Torah in this week’s parshah mandates that for animals to be kosher they must possess two characteristics – they must have cloven hooves and chew the cud (Leviticus 11:3).

In contemporary times there is much ado about the impact of food on physical health. My doctors keep telling me, for example, to keep the fat and cholesterol down. Is it possible that food could similarly impact on one’s spiritual well being? This in fact is the position of Rabbi Samson Raphael Hirsch in his explanation of kashrut.

The characteristics of kosher animals point to their being more passive in nature. In Hirsch’s words: “If we look at the signs for clean animals they appear plant-like. As they chew the cud, the food consumed passes through two stomachs, is driven up the gullet again and chewed for the second time. Thus, these animals spend a great deal of time in the absorption of food. The cloven hooves of the permitted animals also seem to have been created more for the mere purpose of standing than for being used as weapons or tools.”

The same is true concerning fish. To be kosher, fish must have fins and scales (Leviticus 11:9). Not coincidentally, fish that have these characteristics are by and large more peaceful in nature. The more aggressive fish fall into the category of the prohibited. Moreover, birds of prey are by and large enjoined. The rule holds fast. The more aggressive animals and fowl are prohibited. The more passive are permitted.

Of course, not everyone who consumes kosher food leads a life of inner peace. There are troubled people who eat kosher, just as there are fine people who do not eat kosher. Nonetheless, the ritual of kashrut may help us become more conscious of our responsibilities to live ethical lives.

The balance between outer action and inner feelings is especially discernible in the laws of forbidden and permitted animals. Note that chewing the cud is an internal characteristic as it deals with the inner digestive system. In contrast, cloven hooves are an external characteristic. One merely has to look at an animal’s foot to detect whether this criterion has been met. Perhaps this teaches that to be kosher, one’s behavior must not only be outwardly correct but inwardly pure.

Whether these rationales are satisfactory or not, the prohibited foods teach us discipline. They remind us that in the end, God is the arbiter of right and wrong. Notwithstanding, the kashrut laws carry powerful ethical lessons that can help ennoble and sanctify our lives.

    A very acceptable explanation

  2. Makes sense. I'm guessing catfish aren't kosher either, since they don't have scales like most other fish, which makes sense, as catfish are also bottom-feeders and have higher levels of mercury than other fish. It also makes sense not to eat the carnivores in nature, throwing off the delicate balance found in the animal kingdom. Whatever it is, I'm pretty sure Spam isn't kosher either….it's great for a heart-attack though with all the salt and fat. I could go kosher easy….I can't afford lobster anyways, so it's not like I'd miss anything.

    And your doctor is wrong: fat and cholesterol are needed for most people, high amounts of fatty food are not.

‘All Agree That They Are Exempt’

Question: If Abraham was commanded to circumcise his descendants on the eighth day, why do Arabs – who claim to descend from Abraham through Yishmael – wait until their children are 13 to circumcise them? I am aware that this is a matter of little consequence to our people. Nevertheless, this inconsistency is one that piques my curiosity.

Why would the exemption of women from donating the half shekel exempt them from davening Musaf?

This concept should be very relevant to us as we, too, should be happy beyond description.

The Holocaust was the latest attempt of Amalek to destroy the special bond that we enjoy with God.

One can drink up to the Talmud’s criterion to confuse Mordechai and Haman-but not beyond.

“The voice is the voice of Yaakov, but the hands are the hands of Esav” gives great insight to Purim

Purim is the battleground of extremes, Amalek and Yisrael, with Zoroastrian Persia in between.

One should not give the money before Purim morning or after sunset.
