Exame da filosofia de Nietzsche sob o ponto de vista político

O tema da existência ou inexistência de uma filosofia política nietzschiana é recorrente nos meios acadêmicos, e é imensamente problemático desde a vinculação do nome do filósofo às ideologias fascistas da primeira metade do século XX. Especialmente a partir da segunda metade do século XX, a filosofia de Nietzsche tem sido trazida para os debates políticos, dessa vez como uma filosofia das grandes causas, daqueles que buscam a libertação do jugo dos grandes esquemas políticos da modernidade. O objetivo inicial desta dissertação é demonstrar que filosofia de Nietzsche não possui as características que permitam a sua assimilação pelo debate político. O próprio filósofo, reiteradamente, negou-se a ingressar no debate político de seu tempo, recusando-se a limitar seu exame da filosofia e suas reflexões às necessidades e clamores da plebe. Ele alertou para a dureza e radicalidade de seu pensamento, antecipando a vinculação de seu nome a coisas terríveis. Em vista disso, pretende-se levar a cabo nesta dissertação um exame da filosofia nietzschiana sob o ponto de vista da política, isto é, tentar ver se ao quadro geral da filosofia política pode-se juntar o pensamento de Nietzsche. Este exame deve ser feito levando-se em conta o amplo auditório ao qual se destinam os discursos políticos, o vínculo dos discursos políticos aos clamores da plebe, ou ao discurso de dominação. O objetivo final desta dissertação será demonstrar que fora do âmbito da filosofia, isto é, trazida para o seio do senso comum, a filosofia de Nietzsche, dado o caráter controvertido de suas asserções, acaba sendo presa fácil, mais uma vez, dos discursos de dominação e servindo aos piores propósitos. Corre-se o risco, outra vez, de se confirmar o vaticínio do filósofo quanto a sua vinculação a coisas terríveis.

Construction and Operation of a Two-place Diver's Sled

Fisheries gear researchers have employed scuba diver-operated sleds to evaluate towed fishing systems since the early 1950's. One of the earliest sled designs was a converted Stokes litter in which two divers sat tandem with the forward diver operating the diving controls (Sand, 1956). The litter was relatively easy to maneuver and provided a comfortable platform for observing operational fishing gear. However, the use of underwater photographic equipment to document gear performance was difficult due to the limited mobility of the observer-cameraman.

Effects of extremely low-frequency electromagnetic fields on morphine-induced conditioned place preferences in rats

In the present study, we examined the effects of extremely low-frequency (ELF) electromagnetic fields on morphine-induced conditioned place preferences in rats. During the conditioning phase (12 days), three groups of rats were placed in a sensory cue-defined environment paired with morphine (10 mg/kg, i.p.) following exposure to either 20 Hz (1.80 mT) or 50 Hz (2.20 mT) or sham electromagnetic fields for 60 min/day, respectively, and were placed in another sensory cue-defined environment paired with physiological saline (1 ml/kg, i.p.) without exposure to electromagnetic fields. After finishing 12 days of conditioning, preference tests for the morphine-paired place were performed during a 10-day withdrawal period. The exposure to electromagnetic fields substantially potentiated morphine-induced place preferences in rodents, suggesting that ELF electromagnetic fields can increase the propensity for morphine-induced conditioned behaviors.

Effects of scopolamine on morphine-induced conditioned place preference in mice

It is well known that the cholinergic system plays a crucial role in learning and memory. Psychopharmacological studies in humans and animals have shown that a systemic cholinergic blockade may induce deficits in learning and memory. Accumulated studies h

Pentylenetetrazole-induced status epilepticus following training does not impair expression of morphine-induced conditioned place preference

Learning and memory play an important role in morphine addiction. Status epilepticus (SE) can impair the spatial and emotional learning and memory. However, little is known about the effects of SE on morphine-induced conditioned place preference (CPP). Th

Irregular morphine administration affects the retention but not acquisition of conditioned place preference in rats

Drug addiction is increasingly viewed as the expression of abnormal associative learning following repeated exposures to the drugs of abuse Previous I studies have demonstrated that the patterns of repetition such as frequency and spacing are important to many kinds of learning and memory retention We hypothesized that drug repetition pattern might affect the reward-related learning although the total doses of the drug were the same. In the present study, we tested morphine-induced place preference following either regular or irregular pattern of morphine pairing in rats Regular morphine group received morphine administration daily at a regular time with the same dose Irregular morphine groups received morphine administration either at the same time but irregular doses, irregular time but same dose, or irregular time and irregular doses. We found that rats, who received irregular morphine pairing, exhibited similar acquisition of peace preference but different preference retentions compared with regular morphine-treated rats after the same total dose of morphine Rats, who received morphine administration at the same time but irregular doses and at irregular time and irregular doses, showed rapid disruption of place preference than the regular morphine group. Rats, who received morphine at irregular time but the same dose, showed similar retention of place preference to regular morphine group Our results suggest that the pattern of drug pairing plays an important role in the retention of reward-related memory This study may provide new evidence to broaden our understanding of the development and maintenance of drug craving (C) 2009 Elsevier B V.
