The Internet, like the steam engine, is a technological breakthrough that changed the world.

Somebody who eats twice as much factory-farmed products as he or she needs to is clearly doing twice as much damage to the planet. From a utilitarian point of view, that's twice as bad.

More often there's a compromise between ethics and expediency.

We see things like reciprocity which are fairly central to our view of ethics. But if you're talking about a set of worked-out rules on what we are supposed to do then, yes, it is a human product.

It is a mistake to assume that the law should always enforce morality.

The most callous, stupid things were done just because regulations required them...It was not until 1983, for example, that U.S. federal agencies stated that substances known to be caustic irritants such as lye, ammonia, and oven cleaners, did not need to be tested on the eyes of conscious rabbits.

All the arguments to prove man's superiority cannot shatter this hard fact: in suffering, the animals are our equals.
