Human Nature Intrinsic similarities shared by all humans Humans resemble humans. Each of us shares a long list of intrinsic similarities to all other humans. These similarities extend across the sexes, races, and cultures and include many details of anatomy, behavior, and mental processes. Fish swim, birds fly, horses gallop, and humans walk upright.
By Jeffrey Lockwood I have been attacked by animals for thirty years.
Working at a veterinary clinic in high school, I learned the skill of keeping snarling dogs at bay with a squeegee and the art of restraining injured cats. Later, in college research laboratories, I encountered the occasional frightened rat willing to use its yellowed incisors in self-defense.
The mice seemed less The nature of violence in human, but were quicker to draw blood if carelessly handled.
But I was unprepared for the unmitigated ferocity of the Gryllacrididae — insects that look like a cross between a cricket and a grasshopper. My research as a professor at the University of Wyoming had focused on grasshoppers, and I had the opportunity to spend a sabbatical leave in Australia working with their relatives.
While grasshoppers can be feisty, kicking and struggling valiantly when held, gryllacridids are fierce. Lifting their wings to appear larger and thumping their abdomen against the ground like a war drum, they launch themselves at any intruder.
Gryllacridids attack in order to live. These creatures lack standard insect defenses — they have no stench, toxin, or sting.
In coloring they tend toward drab, earthy shades. Their nests, whether subterranean burrows or mats of dried leaves, are invisible during the light of day. And finally, gryllacridids are strictly nocturnal, avoiding the visually oriented birds that constitute the primary predators of many insects.
There are, however, plenty of nocturnal hunters seeking a midnight snack. So, when stealth fails and a gryllacridid perceives that it is faced with imminent death, it unleashes a maniacal display of mandible-gnashing, abdomen-thumping, wing-flapping ferocity.
These savage creatures gave me ample opportunity to ponder the nature of violence. Starting a new line of study in a novel place reminded me of my first days of graduate school a dozen years earlier.
Jeff LaFage taught my graduate course in insect behavior at Louisiana State University with passion and intensity. He was a demanding and kind teacher, a true scholar and Renaissance man — studying the evolution of termite sociality, collecting Tiffany glass, and hosting a Baroque music program on public radio.
He was unable to harm a fly without reason, but when he peered over the wire rims of glasses perched menacingly on his nose, a student who had failed to read the assigned paper or otherwise prepare for the semiweekly grilling cringed. Through the fall semester ofDr.
LaFage revealed to us the ways of insects: He would often use imaginative ecological and evolutionary scenarios to set up a series of Socratic questions that would elicit from us the answers about the complex origins of behavior. LaFage explained, is a function of how an animal perceives itself and the environment, as constrained by evolution and experience.
Insects rely heavily on instinct, which serves them well. For example, many insects respond to a sudden surge of carbon dioxide, a sure indication that a large mammal is nearby. For mosquitoes this gas is a chemical dinner bell. But a huff of breath on a flower head induces thrips to hastily abandon their refuge.
Like a swarm of living commas, they evacuate rather than risk being consumed by a lumbering grazer oblivious to their presence. Similarly, many social insects such as bees and ants rush from their nests when carbon dioxide pours in, but theirs is a charge rather than a retreat: For a man of such a gentle, albeit intense, demeanor, Dr.
LaFage seemed to relish his review of the insectan arsenal. These creatures have mouthparts variously adapted for crushing, dismembering, slicing, and piercing.
The most remarkable structures are those whose original function was co-opted for assault.Violence is an assault on community, on belongingness, on relationship We spend the rest of the semester reading books and articles that apply this idea to the violence in our lives—to how domestic violence and racism and poverty and militarism and the war on the environment all rip apart the dream of “gathered togetherness,” of real community.
A Treatise of Human Nature (–40) is a book by Scottish philosopher David Hume, considered by many to be Hume's most important work and one of the most influential works in the history of philosophy.
The Treatise is a classic statement of philosophical empiricism, skepticism, and torosgazete.com the introduction Hume presents the idea of placing all science and philosophy on a novel. Human Nature, Intrinsic similarities shared by all humans.
Humans resemble humans. Each of us shares a long list of intrinsic similarities to all other humans. The study, published today in Nature, looked at the probability of dying at the hands of another person in more than human populations dating back to the Paleolithic torosgazete.com since humans are not the only animals that kill members of the same species, the team collected information on violent behavior among related species as well.
The human nature of violence Opinion Aug 02, by Jeff Morris Hamilton Spectator A woman writes a message on a makeshift memorial remembering the victims of the Danforth shooting in Toronto, which killed two and injured The Better Angels of Our Nature: Why Violence Has Declined is a book by Steven Pinker, in which the author argues that violence in the world has declined both in the long run and in the short run and suggests explanations as to why this has occurred.
The book contains a wealth of data simply documenting declining violence across time and geography.
