Astrology and Naturphilosophie: A Case of Johann Wilhelm Andreas Pfaff (1774-1835)
No full textJohann Wilhelm Andreas Pfaff (1774-1835) był obiecującym niemieckim matematykiem i astronomem, należącym do bogatej w tradycje akademickie rodziny Pfaffów – miał dwóch starszych powszechnie znanych braci. Niniejszy artykuł przedstawia życie najmłodszego z Pfaffów – od czasu jego studiów teologicznych w Getyndze do okresu działalności w Uniwersytecie Erlangeńskim. Krocząc śladami Klaudiusza Ptolemeusza i Johanna Keplera, Johann Wilhelm Andreas Pfaff usiłował promować astrologię w pierwszych dekadach XIX wieku. Jego wysiłki umocnienia astrologii jako pełnoprawnej dyscypliny akademickiej, zamiast oczekiwanego skutku, spotkały sią z opozycją, drwiną i marginalizacją samego Pfaffa w ówczesnej społeczności akademickiej. Jednakże jego osobisty dramat powinno się umiejscowić w szerokim kontekście nurtu tzw. Naturphilosophie – romantycznego ruchu myślowego, niezwykle popularnego w kręgach intelektualnych ówczesnych krajów niemieckich (także w państwach skandynawskich).Johann Wilhelm Andreas Pfaff (1774-1835) was a promising German mathematician and astronomer belonging to the rich in academic traditions family—he had two well-known older brothers. The present paper describes life of the youngest of Pfaffs since his theological studies in Göttingen to the time of his activity at the University of Erlangen. Following the footsteps of Claudius Ptolemy and J. Kepler, Johann Wilhelm Andreas Pfaff tried to promote astrology in the first decades of the 19th century. His efforts to strengthen astrology as a full-fledged academic discipline, instead of the expected effect, have resulted in opposition, mockery and his marginalisation in contemporary academic community. However, such personal drama of this scholar should be considered in a wider context of so-called Naturphilosophie—romantic intellectual movement, extremely popular in the contemporary intellectual circles of the German states (as well as in the Scandinavian countries)
Pfaff, D. Drive
No full textDonald W. Pfaff. Drive: neurobiological and molecular mechanisms of sexual motivation
What arouses an animal or human from an inactive, nonresponsive state to a condition of activity and responsiveness? What are the biological mechanisms for this change? In this book, Donald W. Pfaff focuses on a reproductive behavior typical of many female animals. Sensory stimuli from the male trigger responses in a well-defined circuit of nerve cells. At the top of the circuit, certain nerve cells receive and retain sex hormones such as estrogens and progesterone. As a result, specific genes in these nerve cells are turned on at specific times, affecting, in turn, the rest of the neural circuit and causing a state of sexual responsiveness.
According to Pfaff, the biological bases for the most primitive human drives are largely explained by mechanisms uncovered in animal brains that have not changed in their fundamental properties over millions of years of evolution. Focusing on a single instinctive behavior, in this case, the sex drive is an important step toward understanding the biological reasons for the change from unmotivated to motivated animal behavior.https://digitalcommons.rockefeller.edu/ru-authors/1146/thumbnail.jp

Brain arousal and information theory neural and genetic mechanisms
No full text"Donald Pfaff argues that, beneath our mental functions and emotional dispositions, a primitive neuronal system governs arousal. Employing the simple but powerful framework of information theory, Pfaff revolutionizes our understanding of arousal systems in the brain. Applying his hypothesis to heightened states of arousal - sex and fear - Pfaff shows us how his theory opens new scientific approaches to understanding the structure of brain arousal. Brain Arousal and Information Theory challenges current thinking about cognition and behavior. Whether you subscribe to Pfaff's theory or not, this book will stimulate debate about the nature of arousal itself."--BOOK JACKET

Social Neuroscience: Complexities to Be Unravelled
No full textThe use of hormone actions to help unravel brain mechanisms for behavior has led to several striking successes in analyzing neural circuits and cellular mechanisms for social behaviors. This success has prompted us to look forward and speculate about the essential nature of the most complex social behaviors. We propose that there are several aspects that distinguish social neuroscience fromneuroscience more generally. One notion is that the nature of human social behavior is qualitatively different from that of any other species and was perhaps a key driving force behind the evolution of the human mind and brain. Other speculations involve the normative aspects of social behaviors, both prosocial and antisocial. Bringing complex social behaviors into the laboratory for systematic analysis will pose one of the major challenges for experimenters in our field
