Why Are We Not Vegetarians?

Question:
If Judaism requires us to be kind to animals, shouldn't we be commanded to be vegetarians?
______
Answer:
I have the utmost respect for anyone,who chooses not to eat meat, out of concern for animal welfare. And there have been some who have suggested, that this is in keeping with Judaism's ideals, (although all agree, that Judaism allows eating meat).

But there is another way of looking at it, a more spiritual angle, that reveals, that eating meat is not just an accommodation to human desire, but has a holy purpose.
_______
The Talmud teaches, that the reason Adam and Eve were created after all other creatures, was to teach them a dual lesson: humans can be either the pinnacle of creation, or its lowest life-form.

If they act appropriately, then everything was created just to serve them; but if they debase themselves, then they should remember that, "even a flea preceded you."

The human being is the only creature, with free-choice. This means, that we can either work on ourselves, and become better than our nature; or abuse our gifts, and become worse.

Only a human can be, generous, kind, selfless, and act higher than his or her instincts; and only a human can be, cruel, destructive and murderous.

(Although sometimes animals do what seem like acts of kindness or destruction, they are invariably just following their instinct for survival -- there is no altruism or malice, in their actions.)

When we use our freedom, to act in a kind, holy and selfless way, we are the highest life form, and the rest of creation is there to serve us.

Then, by eating other creatures, we are in fact elevating them, to places where they couldn't go by themselves.

For example, if I eat a tomato, and then use the energy in that tomato, by doing an act of kindness; the tomato then has become a partner in my action; thus making the world a better place -- something a tomato can't do on its own.

On the other hand, if I use my energy, only to further selfish goals, or to oppress or inflict harm, then what right do I have to eat a tomato? The tomato never hurt anybody, and by eating it and causing harm, I am corrupting an innocent tomato!

This is why Judaism doesn't see eating animals, as necessarily being cruel. In fact, it could even be cruel not to eat animals, because you are robbing them of a chance, to serve a higher purpose, (unless of course it is for health reasons).

However, if you yourself are not living a life of purpose, then it is just as cruel, to eat a tomato, as a chicken!

If the physical world is your only reality, then you have reason to feel guilty when you consume other life forms. But when you see the spiritual world as just as real (if not more), then even eating can become holy, and we thereby become partners with G-d in the creation.
