I believe that you think that you are, but I don't see any evidence you
actually are facing up to them. When you encounter one of these difficulties
your apparent response is to acknowledge it, label it and file it away in a
folder called "difficulties", then you carry on as before, the fundamental
beliefs and conclusions that you had before encountering the difficulty
remain unscathed. It's as if you find AR ideals so compelling, so
comforting, that you have abandoned all real critical thought regarding
them. You think that perhaps some solution will emerge to resolve the
difficulties if you just leave them stored away long enough? De Grazia's
"equal consideration" is one example of this phenomenon that comes to mind.
You seem to find the notion so intuitive, so appealling, that even De
Grazia's own admitted doubts and confusion over the concept don't deter you
from viewing it as a de facto fundamental moral imperative. >> Stay informed about: The myth of food production "efficiency" in the "ar" debate |

Yeah, but you're wrong. There's no rational reason for be to abandon
equal consideration. If someone offered a good defence of species
discrimination, that might make it rational for me to do that.

Look, I'm telling you what meaning was intended for the phrase by the
person who invented it. You think he's come up with the wrong phrase
for what he means, well, you're entitled to your view, but seriously,
what would you know? You're really not competent to comment on this
issue.

I have read the explanation DeGrazia gave of the notion, and I know

Look, this is just stupid anti-intellectualism. Moral philosophers
have spent more time thinking about ethical theory than you have.
There may be some concepts they can usefully employ which it might
take you a little while to understand. I mean, do you expect to be
able to understand all the concepts in my thesis (which is in
mathematics) just from "common sense" alone? You don't get what "equal
consideration" means. Acknowledge that fact, and if you feel inclined,
try to do the necessary study to understand the term, or else
acknowledge that you're not competent to say all that much about it.

Well, I'm not abandoning equal consideration as I or DeGrazia
understand it. You haven't managed to grasp that concept, you should
acknowledge that and concede that you're not competent to say anything
about it.

Yeah, you think it's obvious that taking equal consideration seriously
would require the extinction of our species. Well, I don't think
that's obvious. And I understand the concept and you don't. So you
should really acknowledge that you have no basis for saying that I'm
not taking the difficulties in my position seriously, because you
don't really understand what I am committed to.

Well, it's not as simple as that, I'm afraid. I can see that your lack
of background in moral philosophy is giving you trouble understanding
the concept. I can try and help you if you like, but you may have to
do a bit of reading. You'll also have to give me credit for not
engaging in "circuitous sophisms". I'm not. If you don't accept that,
well, that's really not my problem.

"Equal consideration" is a good phrase for what he means. You would
understand this if you were more familiar with the different schools
of thought in moral philosophy and their different approaches to the
issue of what human equality means.

No, I'm afraid you're not. It's not just the kind of thing that common
sense and competence in English gives you an insight into. You've got
to have some familiarity with the attempts by different moral
philosophers to explain what we mean by equality.

Not to you, maybe. My explanations are not sophisms. I may not be
doing a very good job of helping you at the moment. Some concepts take
time to explain. If you're prepared to listen and make a genuine
effort to understand we can work through the book again and I can
refer you to some other literature which may help you. I think my
explanations should have helped you at least a little bit. I think
you're not really making a good faith effort to understand. You've
just decided that there's nothing to understand.

You're not competent to evaluate DeGrazia's work in moral philosophy
when you don't know the context which it fits into.

You're refusing to make an effort to understand what "equal
consideration" is really supposed to mean. What about your other
point, we spend money on ourselves instead of feeding the starving so
we don't give equal consideration to humans either? All right, in that
sense of equal consideration we don't, no. But it's silly to assume
that that's the only sense of equal consideration worth examining.

No, I'm afraid it hasn't. The concept of discrimination on the basis
of species is linked to the concept of equal consideration. If you
don't understand one, you don't understand the other. And if you don't
understand the concept of discrimination on the basis of species, you
can't rigorously establish anything about it. If you want to make a
respectable criticism of DeGrazia's ideas, you're going to have to
make a better effort to understand them. Your current attempts aren't
good enough. You're not manifesting any real understanding.

Well, look, I'm sorry you find it tiresome, but I'm afraid it's true.
I find it pretty tiresome that you keep on carrying on as though
you're competent to criticize these ideas when you obviously don't
understand them, and that when I try to educate you you say I'm
engaging in sophisms.

That's a silly argument. There's no reason to think demodex mites are

Of course, that's what rational thought is supposed to allow you to do. That
doesn't mean you can't reassess the position at any time.

Why does it require justification? It seems to me that doing so is inherent
in the very fabric of existence. Equal consideration, taken literally, which
one must do or else find a new phrase, implies behaviours that are
impossible to achieve.

The phrase seems to say it all.

In other words it's a term that philosphers bandy about whilst sitting
sipping lattés in college lounges, don't expect it to sound reasonable to
someone who is trying to apply it with common sense.

Discrimination of the basis of species is as much an inherent part of our
reality as animals, and as humans as birth and death.

As it stands, at this moment in time, you are abandoning equal
consideration, as I understand it, when you realize the fact that in order
to live your relatively comfortable existence in western academia you are
sponsoring the systematic killing of animals. This state of affairs in no
minor hurdle, life for our species could go on if we did not do this. We
even kill animals when we cut our lawns or wash our bodies. This life is a
bloody affair. Ironically, if we actually pursued this notion to the

Yeah, but you're wrong. There's no rational reason for be to abandon
equal consideration.

You never embraced it, it's just a phrase you like the sound of.

It doesn't require a defense, you can't live on this earth and not

Well, maybe you should pay more attention to the explanations given by

Look, I'm telling you what meaning was intended for the phrase by the

He has no authority to assign meaning to words that don't conform to their

You think he's come up with the wrong phrase

No, it's anti-pseudo-intellectuallism.
Moral philosophers
have spent more time thinking about ethical theory than you have.
There may be some concepts they can usefully employ which it might
take you a little while to understand. I mean, do you expect to be
able to understand all the concepts in my thesis (which is in
mathematics) just from "common sense" alone? You don't get what "equal
consideration" means. Acknowledge that fact, and if you feel inclined,
try to do the necessary study to understand the term, or else
acknowledge that you're not competent to say all that much about it.
---->
I know that "equal consideration" could not remotely apply to any way that
humans could systematically relate to non-humans. A human could conceivably
value a beloved dog as much as he values his child, even that is unlikely.
In fact every consideration we have towards other beings is unique to the
relationship between us and each of them. None of them is equal.

Well, I'm not abandoning equal consideration as I or DeGrazia
understand it. You haven't managed to grasp that concept, you should
acknowledge that and concede that you're not competent to say anything
about it.

Not members of the animal kingdom when we wash our bodies, I don't
think.

No? http://en.wikipedia.org/wiki/Demodex_mite
You didn't comment about mowing the lawn, have you ever sat outside at night
under a big light and watched the life in a lawn? There are millions of tiny
creatures, whole bug worlds spring up in a few weeks. They are laid waste
when we cut the grass.

Yeah, you think it's obvious that taking equal consideration seriously
would require the extinction of our species. Well, I don't think
that's obvious. And I understand the concept and you don't. So you
should really acknowledge that you have no basis for saying that I'm
not taking the difficulties in my position seriously, because you
don't really understand what I am committed to.
---->
You're not saying anything of substance. I have demonstrated in this post
that "equal consideration" can't really mean equal because we kill demodex
mites when we wash our hair. We also kill small creatures when we wash our
clothes, vacuum the carpet, walk, even breathe. So you must least take the
step of stipulating that size matters. The problem with that is though, it
doesn't stop with mites, the continuum.. continues. It keeps going up
through beetles and grasshoppers, roaches, toads, lizards, finally mammals.
Animal life is ubiquitous, we're part of an animal soup. It's difficult
enough to give some kind of consideration to some people, much less every
animal in existence. It's just not a plausible concept. It does have a nice
ring to it though, I'll give you that. AR is all about concepts that have
nice rings to them, people love that. >> Stay informed about: The myth of food production "efficiency" in the "ar" debate |

Actually, this thread began by Mr Rudy posting an elegant argument on the
issue. Since then you have simply been barking back, asserting that are not
convinced, inserting numerous references to how qualified you are to talk on
these matters and whining about being insulted. >> Stay informed about: The myth of food production "efficiency" in the "ar" debate |

That's right. There are two arguments, an environmental argument and
an argument from fairness of global food distribution. Ball has not
touched either of these, by his own admission. He is making the
bizarre and ridiculous interpretation that the argument is about
resource-intensiveness alone and attacking that version of the
argument.

As he himself concedes, his argument only bears on an argument from
resource-intensiveness alone. I maintain what I think should be fairly
obvious, that this is an argument nobody actually makes. This
shouldn't be too hard to understand if you've been listening.

Yes, that is one other point he made. I haven't really gone into this
in any depth, although I have made some remarks. That's a different
issue.

Unless you're seriously claiming our level of crop production is no
higher than it would be if we were all vegan, I don't see what the
point is.

I'm not naive enough to believe that if the developed world went vegan
that would solve the world's food distribution problems. I believe
that the argument that if we weren't producing so many crops to feed
animals, the market price of certain crops would be more affordable to
people who are starving, deserves some consideration, however.

There's really nothing wrong with the environmental argument. It's
perfectly reasonable to point out that going vegan is one rational
thing to do from an environmental point of view. Obviously no-one's
going to do absolutely everything they can to minimize their impact on
the environment, but cutting down on animal products is nevertheless
one reasonable step to take. >> Stay informed about: The myth of food production "efficiency" in the "ar" debate |

People who eat meat are never prevented from switching to a vegetarian diet
due to guilt, or fear of doing something immoral, they just don't want to
give up something they like a lot. So it's not a psychological barrier.

Yes, they actually are. Diet is not normally considered to be a major moral
issue except by vegans, so a non-vegan who decides they want to explore the
health benefits of a vegan diet is unlikely to feel a moral barrier to
making such a change, that would not even come up as an issue. However, a
vegan who is used to thinking of their diet as a statement of moral
commitment, which is most of them, is very likely to have psychological
barriers or hangups preventing them from starting to eat meat. >> Stay informed about: The myth of food production "efficiency" in the "ar" debate |

'There is a popular notion that anthropology can offer useful
insights for forming the basis of a dietary philosophy.
Anthropology is a science which is only just starting to mature,
previously having been little more that a systematic, but lose,
body of "say-so" information which attempted to explain our
species history and origins. With advances in dating methods,
including DNA analysis and more fossil finds, the science is
now embarking on its integration with biology. Previously,
anthropology was a pseudo-scientific marriage of traditional
views attempting to link the findings of robust sciences, such
as geology, palaeontology and archaeology. However, even
though anthropologists like Richard Leakey are aware that
their 'science' is often "based on unspoken assumptions"
(The Making of Mankind, p. 82, R. Leakey), they show that
they will persist in making them.
Anthropologies 'Man The Hunter' concept is still used as a
reason for justifying the consumption of animal flesh as food.
This has even extended as far as suggesting that animal foods
have enabled or caused human brain enlargement. Allegedly
this is because of the greater availability of certain kinds of
fats and the sharing behaviour associated with eating raw
animal food. The reality is that through natural selection, the
environmental factors our species have been exposed to
selected for greater brain development, long before raw animal
flesh became a significant part of our ancient ancestors diet.
The elephant has also developed a larger brain than the human
brain, on a diet primarily consisting of fermented foliage and
fruits. It is my hypothesis that it is eating fruits and perhaps
blossoms, that has, if anything, contributed the most in allowing
humans to develop relatively larger brains than other species.
The ability of humans to develop normal brains with a dietary
absence of animal products is also noted.
...
Given a plentiful supply of fruits the mother does not have to
risk expending much of her effort obtaining difficult to get foods
like raw animal flesh, insects, nuts and roots. Furthermore, fruits
contain abundant supplies of sugars which the brain solely uses
for energy. The mother who's genes better dispose her for an
easy life on fruits would have an advantage of those who do not,
and similarly, the fruit species which is the best food for mother
and child nutrition, would tend to be selected for. There is now
little doubt amongst distinguished biologists that fruit has been
the most significant dietary constituent in the evolution of humans.

What are the essential biochemical properties of human
metabolism which distinguish us from our non-human primate
relatives? One, at least, is our uniquely low protein requirement
as described by Olav T. Oftedal who says:
"Human milk has the lowest protein concentration (about 7% of
energy) of any primate milk that has been studied. In general, it
appears that primates produce small daily amounts of a relatively
dilute milk (Oftedal 1984). Thus the protein and energy demands
of lactation are probably low for primates by comparison to the
demands experienced by many other mammals." The nutritional
consequences of foraging in primates: the relationship of nutrient
intakes to nutrient requirements, p.161 Philosophical Transactions:

One might imagine that given our comparatively 'low protein' milk,
we would not be able to grow very fast. In fact, as the image on the
right shows, human infants show very rapid growth, especially of
the brain, during the first year of life. Human infants are born a
full
year earlier than they would be projected to, based on comparisons
with other animals. This is because of the large size their brains
reach. A human infant grows at the rate of 9 kg/year at birth, falling
to 3.5 kg/year a year later. Thereafter its growth rate is about half
that of a chimpanzees at 2 kg/year vs. about 4.5 kg/year. Humans
are relatively half as bulky as the other great apes, thus allowing
nutrients to be directed at brain development and the diet to be less
demanding. The advantages of such an undemanding metabolism
are clear. Humans delay their growth because they 'catch up' later,
during puberty as seen on the graph. Even so, the growth rate never
reaches that of a newborn infant who grows best by only eating
breast milk.

According to Exequiel M. Patiño and Juan T. Borda 'Primate milks
contain on the average 13% solids, of which 6.5% is lactose, 3.8%
lipids, 2.4% proteins, and 0.2% ash. Lactose is the largest
component of the solids, and protein is a lesser one'. They also say
