Maxist said:It is a good argument, but you neglect one other reason that we are unalike from other mammles. Our level of conciencness and our level of intellegence is another deciding factor. Our cranial capacity is a decisive factor, which does make us better than other mammals. If the mammal has never made a particular contribution to society other than killings or allowing to live, how can it possibly be considered at the level of a mammal who has?
What bizarre and speciesist ideas!
There's no reason to believe our "level of consciousness" isn't exactly the same as any other mammal.
You seem to be basing your concept of "betterness" on intelligence and contributions to society. I'll ignore cranial capacity, as many large animals have greater capacities than hominids and I assume you meant to tie it in to intelligence.
If goodness is based on intelligence then bright people are better than dim ones. I think most people would dispute this.
Intelligence gives us flexibility and the ability do dominate other animals and exploit our environment creatively, but other animals have other abilities that enable them to do similar things. Some animals are faster, some have better senses of smell, sight or hearing. All animals except hominids seem able to establish a place for themselves in the life-web and exploit it indefinitely. You could make the case that any of these superior qualities would make a species "better" than humans.
Your mention of "contributions to society." This strikes me as an incredibly arrogant and species-centered concept.
It is not another animal's job to contribute to society. They do not exist to serve us. They might, in fact, well condemn us for not contributing to their societies. We are, in fact, destroying many of their societies with our campaign of environmental and habitat destruction.
It is the "job" of an organism to play its part in the maintenance of the global life-web that keeps our planet alive and healthy.
A deer must have a forest. A forest must have proper soil. Proper soil must have a fungal network. A fungal network must have a healthy bacterial community, &c, &c, &c. Organisms are intricately woven into their environments. Life depends on each doing its job. Those that do their jobs are "better" than those that do not.
Hominids do not do their jobs. They have removed themselves from the ecological life-web and become parasitic. They destroy the ozone shield, pollute the atmosphere and water. They change the climate, sterilize the soils, desertify the land.
We are in the midst of a catastrophic collapse of the planetary ecology. (The last such collapse was 65,000,000 years ago). This planetary die-off is due entirely to the efforts of a single species.
Are we the best species, Maxist, or the worst?
