Spinoza, Baruch
Baruch, or Benedictus, Spinoza (1632–77) is the author of works, especially the Ethics and the Theological-Political Treatise, that are a major source of the ideas of the European Enlightenment. The Ethics is a dense series of arguments on progressively narrower subjects – metaphysics, mind, the human affects, human bondage to passion, and human blessedness – presented in a geometrical order modeled on that of Euclid. In it, Spinoza begins by defending a metaphysics on which God is the only substance and is bound by the laws of his own nature. Spinoza then builds a naturalistic ethics that is constrained by, and to some extent is a product of, his strong metaphysics. Human beings are
individuals that causally interact with other individuals and are extremely vulnerable to external influence. They are not substances. Moreover, human beings are bound by the same laws that bind all other individuals in nature, so Spinoza presents accounts of goodness, virtue, and perfection that are consistent with these perfectly general laws. Spinoza’s principal influences include René Descartes, Thomas Hobbes (see hobbes, thomas), Moses Maimonides (see maimonides, moses), the Roman Stoics (see stoicism), and Aristotle (see aristotle). Although his innovative philosophical views undoubtedly contributed to the strong writ of cherem, or ostracism, that Spinoza received from the Portuguese Jewish community of Amsterdam in 1656, his work nevertheless also shows the influence of the study of Scripture and of Jewish law
Spinoza and Hobbes
The English philosopher Thomas Hobbes directly influenced and, possibly, was also influenced by Spinoza. Hobbes and Spinoza were both aware of the advanced science of mid-seventeenth-century Europe and of the uncomfortable fit of that science with traditional moral and religious doctrines. Spinoza defines ‘appetite’ in terms of striving and ‘desire,’ in turn, in terms of appetite. The basis for Spinoza's theory of desire in an account of causation implies that the distinction between activity and passivity may be incremental. For both Hobbes and Spinoza, the emotions are basic enough to psychology that a theory of them amounts to a theory of human nature: it tells us what, in a very basic way, human beings are like. The chapter addresses the authors’ views on the question of whether and how human beings can change. It presents consequences of the philosophers’ accounts of human nature for their ethics and politics

Activated protein C increases sensitivity to vasoconstriction in rabbit Escherichia coli endotoxin-induced shock
INTRODUCTION: The aim of this study was to investigate the effects of activated protein C (aPC) on vascular function, endothelial injury, and haemostasis in a rabbit endotoxin-induced shock model. METHOD: This study included 22 male New Zealand rabbits weighing 2.5 to 3 kg each. In vitro vascular reactivity, endothelium CD31-PECAM1 immunohistochemistry, plasma coagulation factors and monocyte tissue factor (TF) expression were performed 5 days (D5) after onset of endotoxic shock (initiated by 0.5 mg/kg intravenous bolus of Escherichia coli lipopolysaccharide (LPS)) with or without treatment with aPC injected as an intravenous 2 mg/kg bolus 1 hour after LPS (LPS+aPC group and LPS group, respectively). RESULTS: LPS decreased the sensitivity to phenylephrine (PE) in aortic rings without endothelium (E-) when compared to E- rings from the control group (p < 0.05). This was abolished by N(G)-nitro-L-arginine methyl ester and not observed in E- rings from aPC-treated rabbits. Although aPC failed to decrease monocyte TF expression in endotoxinic animals at D5, aPC treatment restored the endothelium-dependent sensitivity in response to PE (2.0 ± 0.2 μM in rings with endothelium (E+) versus 1.0 ± 0.2 μM in E- rings (p < 0.05) in the LPS+aPC group versus 2.4 ± 0.3 μM in E+ rings versus 2.2 ± 0.2 μM in E- rings (p value not significant), in the LPS group). Endotoxin-induced de-endothelialisation was reduced by aPC at D5 (28.5 ± 2.3% in the LPS+aPC group versus 40.4 ± 2.4% in the LPS group, p < 0.05). CONCLUSION: These data indicate that aPC increased the sensitivity to a vasoconstrictor agent (PE) associated with restoration of endothelial modulation, and protected against endothelial histological injury in endotoxin-induced shock. It failed to inhibit TF expression at D5 after LPS injection
