"To a fair extent the Tyrannosaurus species are the tyrannosaur's of tyrannosaurs; they have taken to an extreme the development of skull size, strength, and power. This and the larger, more forward-pointing mid-upper jaw teeth suggest a more potent wounding ability than the albertosaur's. The stoutness of Tyrannosaurus relative to albertosaurs is readily apparent in the skeletal restorations. They are not as graceful, but they have a well-proportioned, majestic attractiveness of their own."

"This is the theropod. Indeed, excepting perhaps Brontosaurus, this is the public's favourite dinosaur, having fought King Kong for the forced favor of Fay Wray and smashed Tokyo (with inferior special effects) in the guise of Godzilla."

"If not for the long tail, one might mistake a theropod for a big, toothy, marauding bird in the dark. That theropods are birdlike is logical, since birds are their closest living relatives. Remember that next time you eat a drumstick or scramble some eggs."

"How would we think and feel about predatory dinosaurs if they were alive today? Humans have long felt antipathy toward carnivores, our competitors for scarce protein. But our feelings are somewhat mollified by the attractive qualities we see in them. For all their size and power, lions remind us of the little creatures that we like to have curl up in our laps and purr as we stroke them. Likewise, noble wolves recall our canine pets. Cats and dogs make good companions because they are intelligent and responsive to our commands, and their supple bodies make them pleasing to touch and play with. And, very importantly, they are house-trainable. Their forward-facing eyes remind us of ourselves. However, even small predaceous dinosaurs would have had no such advantage. None were brainy enough to be companionable or house-trainable; in fact, they would always be a danger to their owners. Their stiff, perhaps feathery bodies were not what one would care to have sleep at the foot of the bed. The reptilian-faced giants that were the big predatory dinosaurs would truly be horrible and terrifying. We might admire their size and power, much as many are fascinated with war and its machines, but we would not like them. Their images in literature and music would be demonic and powerful - monsters to be feared and destroyed, yet emulated at the same time."

"Tyrannosaurus rex did not have 6-to-8-inch serrated teeth and an arc of D-cross-sectioned teeth set in a massive, powerful skull just to consume rotting carcasses! These were killing tools. In sharp contrast are the weak beaks and feet of vultures and condors- the only true living scavengers."

"What gave archosaurs the edge as large predators at this time, and therapsids the edge as smaller ones? Frankly, I am not sure. Both seem to have had heightened metabolic rates and fur or feather insulation... Perhaps the chief advantage enjoyed by thecodonts centered around their big, slashing attack jaws. These may have made them better big-game hunters, while the more precise cutting teeth of therapsids were more suitable for smaller prey."

"Alas, producers of commercial dinosaur products continue to churn out low quality product that is either obsolete or improperly derivative. Dino documentaries and books have become so plentiful that they are no longer special and I do not try to keep up with them. There are also serious problems with quality and accuracy which often fail to meet the expectations of scientists. More about those problems here. I about kicked in the TV screen when one dino doc claimed that the brain of Tyrannosaurus was as large as that of a gorilla when its IQ was not all that much better than a croc’s. And why are the theropods shown pausing to challenge their prey before they charge, when the actual focus of predators is to hit and overwhelm the victim before it knows what is happening? The low standards are not surprising considering how the media and press frequently carry product that promotes belief in the paranormal. But these are quibbles. Dinosaur science has almost completely transformed over the half century that my neural network has been aware of it. The old stand-bys from Allosaurus to the always strange Stegosaurus are still fascinating, but we now know about armored sauropods, fat-bellied therizinosaurs and multi-winged, near avian, sickle claws. The reptile model is out and the avian-mammalian is dominant."

"The biggest living terrestrial predator, the Siberian tiger, at about a third of a metric ton (300 kg) pales in comparison to the biggest of the meat-eating dinosaurs, which reached 5 to perhaps 20 metric tons - the size of elephants and bigger. But while elephants cannot run, the biggest predatory dinosaurs probably ran as fast as horses, and they hunted herbivores that themselves were as big as or bigger than elephants."

"Novelist Michael Crichton wrote Jurassic Park as a screenplay option for the Steven Spielberg flick. I am ambiguous about Crichton’s body of work, as it includes dubious anti-scientific elements. But I can’t be too upset about a fellow who includes me in the acknowledgements of his bestselling novel. I ended up doing some preliminary studies of Tyrannosaurus and Deinonychus for the movie(s). These were significantly altered by Spielberg and Stan Winston and his effects team for copyright purposes. In the film, some of my skeletals show up posted on Sam Neill's (ak.a. Dr. Grant's) trailer wall. I was accidentally responsible for the avian term 'raptor' being improperly applied to dromaeosaurs. In another Hunteria paper and PDW, I synonymized Deinonychus with Velociraptor, which Crichton picked up on and shortened into the convenient handle 'raptor'. The movie was okay, but I will never forgive them for presenting Brachiosaurus as such a heavy limbed clunker. I had nothing to do with that. I thought it was too bad the potentially omnivorous brachiosaurs – which were unlikely to have been as placid as cattle – missed the opportunity to snarf up the bratty kids when they were up in the tree."

"By the Cretaceous crocodilians of essentially modern form were the theropods [sic] main competitors. Yet crocodilians appear to be less abundant in most Mesozoic deposits than they are later in the mammal-dominated Cenozoic. Not only that, but they tended to be small-bodied: few specimens were as big as American alligators or Nile crocodiles. It is possible that theropods were eating the crocs. Even today, big cats once in a while kill a fairly large crocodilian. A tyrannosaur could have swallowed one whole, and gone into the water after them. Constant attacks could have suppressed croc populations, and favored the smaller, harder to catch species."

"The dinosaur world I grew up in was classical. They were universally seen as scaley herps that inhabited the immobile continents. There was no hint that birds were their direct descendents. Being reptiles, dinosaurs were cold-blooded and rather sluggish except perhaps for the smaller more bird-like examples. They all dragged their tails. Forelimbs were often sprawling. Leg muscles were slender in the reptilian manner. Intellectual capacity was minimal, as were social activity and parenting; the Knight painting of a Triceratops pair watching over a baby threatened by the Tyrant King was a notable exception. Hadrosaurs and especially sauropods were dinosaurian hippos, the latter perhaps too titanic to even emerge on land, and if they did so were limited by their bulk to lifting one foot of the ground at a time. Suitable only for the lush, warm and sunny tropical climate that enveloped the world from pole to pole before the Cenozoic, a cooling climate and new mountain chains did the obsolete archosaurs in, leaving only the crocodilians. Dinosaurs and the bat-winged pterosaurs were merely an evolutionary interlude, a period of geo-biological stasis before things got really interesting with the rise of the energetic and quick witted birds and especially mammals, leading with inexorable progress to the apex of natural selection: Man. It was pretty much all wrong. Deep down I sensed something was not quite right. Illustrating dinosaurs I found them to be much more reminiscent of birds and mammals than of the reptiles they were supposed to be. I was primed for a new view."

"Ever since the early '80s I have applied feathers to many of the small dinosaurs, and never did smaller theropods without them. I did so because birds evolved from small theropods, and the evidence for the latter having the high metabolic rates that would have promoted the evolution of insulation was solid. I used to receive endless grief for this. The counter-argument was that no feathers had been found on any dinosaurs, and scales had, so I was engaging in unfounded speculation. But these points were actually not scientific. Scales had been discovered only on large dinosaurs, so illustrating small ones with scales was no less speculative than putting feathers on them. It would be like illustrating little mammals with naked skin if all we had was elephants and rhinos to base mammal integument on. I knew that my thesis was logical, so I bided my time."

"Throughout his career, Kandel has also been a student of the history of neuroscience. ...Kandel's fascination with the "giants" of neuroscience, as he calls them, became ironic when Kandel himself became a part of the history of neuroscience..."

"In the early 1960s, Kandel made the bold decision to conduct research on an unlikely animal, the large sea snail Aplysia californica. Kandel found this invertebrate attractive for neuroscience research because it has fewer and larger neurons than more traditional laboratory animals. This simple neural system would subsequently serve as an invaluable model for understanding the cellular basis of learning."

"The Copernican revolution... revealed that the earth is not the center of the universe... The second, the Darwinian revolution... revealed that we are not created divinely or uniquely but instead evolved from simpler animals by a process of natural selection. The third great revolution, the Freudian revolution of Vienna 1900, revealed that we do not consciously control our own actions but are instead driven by unconscious motives. This... later led to the idea that human creativity... stems from conscious access to underlying, unconscious forces."

"The realization that our mental functioning is largely irrational was arrived at by several thinkers at the same time, including Friedrich Nietzsche... Freud, who was much influenced by both Darwin and Nietzsche... was its most profound and articulate exponent. ...Schnitzler, Klimt, Kokoschka, and Schiele also discovered and explored new aspects of our unconscious mental life. They understood women better than Freud... and they saw more clearly than Freud the importance of an infant's bonding to its mother. They even realized the significance of the aggressive instinct earlier than Freud did. ...Plato discussed unconscious knowledge ...pointing out that much of our knowledge is inherent in the psyche in latent form. ...Hermann von Helmholtz... advanced the idea that the unconscious plays a critical role in human visual perception."

"The fundamental mechanisms that Eric Kandel has revealed [in Aplysia] are also applicable to humans... Even if the road towards an understanding of complex memory functions still is long, the results... have provided a fundamental building stone. It is now possible to continue and, for instance, study how complex memory images are stored in the nervous system, and how it is possible to recreate the memory of earlier events..."

"A brain scan may reveal the neural signs of depression, but a Beethoven symphony reveals what that depression feels like. Both perspectives are necessary if we are to fully grasp the nature of mind, yet they are rarely brought together."

"Much as Leonardo da Vinci and other Renaissance artists used the revelations of human anatomy to help them depict the body more accurately and compellingly, so, too, many contemporary artists may create new forms of representation in response to revelations about how the brain works."

"Viennese life at the turn of the century provided opportunities in salons and coffeehouses for scientists, writers, and artists to come together in an atmosphere that was at once inspiring, optimistic, and politically engaged. ...science was no longer the narrow and restrictive province of scientists but had become an integral part of Viennese culture. ...a paradigm for how an open dialogue can be achieved."

"The Vienna School of Art History, influenced in part by Sigmund Freud's psychological work, began to develop a science-based psychology of art that was initially focused on the beholder. Today, the new science of mind has... again focused on the beholder."

"Reductionism can expand our vision and give us new insights into the nature and creation of art."

"I outline in simple terms... our current understanding of the cognitive psychological and neurobiological basis of perception, memory, emotion, empathy, and creativity. ...the principles of the viewer's response to art are applicable to all periods of painting."

"Modernism began in the mid-nineteenth century as a response not only to the restrictions and hypocrisies of everyday life, but also as a reaction to the Enlightenment's emphasis on the rationality of human behavior. ...The founders of the Royal Society thought of God as a mathematician who had designed the universe according to logical and mathematical principles. The role of the scientist—the natural philosopher was to... decipher the codebook that God had used in creating the cosmos."

"The portraits of the Viennese modernists, with their conscious and dramatic attempts to depict their subject's inner feelings, represent an ideal example of how psychological and biological insights can enrich our relationship with art."

"This dialogue between the ongoing research in brain science and art continue to this day. ...Such dialogues could help us explore the mechanisms in the brain that make perception and creativity possible, whether in art, the sciences, the humanities, or everyday life. In a larger sense, this dialogue could help make science part of our everyday experience."

"One of the characteristic features of Viennese life at this time was the continual, easy interaction of artists, writers, and thinkers with scientists."

"The Age of Insight is a product of my subsequent fascination with the intellectual history of Vienna from 1890 to 1918, as well as my interest in Austrian modernist art, psychoanalysis, art history, and the brain science that is my life's work. In this book I examine the ongoing dialogue between art and science that had its origins in fin-de-siècle Vienna..."

"The function of the modern artist was not to convey beauty, but to convey new truths."

"Science may explain aspects of art but it will not replace the inspiration that art evokes..."

"The intellectual life of turn-of-the-century Vienna is in my blood: my heart beats in three-quarter time."

"The Modernist reaction to the Enlightenment came in the aftermath of the Industrial Revolution, whose brutalizing effects revealed that modern life had not become... mathematically perfect..."

"I was very much influenced by the psychology of Freud and by early workers in the field of learning and memory—James, Thorndike, Pavlov, Skinner, and Ulric Neisser. Their thinking, and even their errors, provided a wonderfully rich cultural background for my later work."

"Nothing is more stimulating for self-education than working in a new area."

"Once I have gotten into a problem, I find it extremely helpful to get a complete perspective, to learn what earlier scientists thought about it. I want to see not only what lines of thought proved to be productive, but also where and why certain other directions proved to be unproductive."

"Having been trained in history and the humanities, where one learns early on how depressing life can be, I am delighted to have ultimately switched to biology, where a delusional optimism still abounds."

"The overarching ideas that have influenced my work and fueled my interest in conscious and unconscious memory derive from a perspective on mind that psychiatry and psychoanalysis opened up for me."

"It is much more meaningful and enjoyable to read the scientific literature about experiments you are involved in yourself than to read about science in the abstract."

"Cori Bargmann... has studied two variants of C. elegans... The only difference between the two is one amino acid in an otherwise shared receptor protein. Transferring the receptor from a social worm to a solitary worm makes the solitary worm social."

"...in various types of organisms, from snails to flies to mice to people. ...learning and memory, as well as synaptic and neuronal plasticity, represent a family of processes that share a common logic and some key components but vary in the details of their molecular mechanisms."

"As astronomy and physics inspired the Enlightenment, so biology inspired Modernism. ...This new view led to a reexamination in art of the biological nature of human existence, as evident in Édouard Manet's Déjeuner sur l’Herbe... Manet's painting... reveals a theme... the complex relationship between the sexes and between fantasy and reality. ...also startlingly modern because of its style. Several decades before Cézanne began to collapse three dimension into two, Manet here had already flattened the viewer's sense of perspective..."

"We now understand that every mental state and every mental disorder is a disorder of brain function. Treatments work by altering the structure and function of the brain."

"I would like to develop a reductionist approach to the problem of attention by focusing on how place cells... create an enduring spatial map only when an organism is paying attention to its surroundings."

"The idea that we are unaware of much of out mental life, first developed by Hermann Helmholtz, is central to psychoanalysis. Freud has added the interesting idea that although we are not aware of most instances of mental processing, we can gain conscious access... by paying attention."

"I have at times felt alone, uncertain, without a well-trodden path to follow. Every time I embarked on a new course, there were well-meaning people... who advised against it. I had to learn early on to be comfortable with insecurity and to trust my own judgement on key issues."

"Like other modern artists faced with the advent of the photography, Klimt sought newer truths that could not be captured by the camera. He... turned the artists view inward—away from the three-dimensional outside world and toward the multidimensional inner self and the unconscious mind."

"Giacomo Rizzolatti... calls these "mirror neurons" and suggests that they provide the first insight into imitation, identification, empathy, and possibly the ability to mime vocalization—the mental processes intrinsic to human interaction. Vilayanur Ramachandran has found evidence of comparable neurons in the premotor cortex of people. ...one can see a whole new area of biology opening up... that can give us a sense of what makes us social, communicating beings. An ambitious undertaking of this sort might... teach us something about the factors that give rise to tribalism, which is so often associated with fear, hatred, and intolerance of outsiders."

"I entered Harvard to become a historian and left to become a psychoanalyst, only to abandon both... to follow my intuition that the road to a real understanding of mind must pass through the cellular pathways of the brain."

"The Viennese Kultusgemeinde... was going bankrupt... European governments typically compensate Jewish agencies... but the Austrian government's compensation was not adequate. ...I owe my existence in the United States to the generosity of the Viennese Kultusgemeinde."

"The history of Austrian culture and scholarship in the modern era largely paralleled the history of Austrian Jewry."
