Prolepsis y justicia en el epicureísmo
The influential 19th century philosophical historiography did not recognize in Epicureanism a political philosophy worthy of study. Based on an analysis of the Principal Doctrines and texts of Hermarchus, Polystratus and Lucretius, this paper aims to show that Epicureans developed a relevant political theory that connected two traditions: the Ionian naturalism and the Socratic reformulation of philosophy as the only true politics. In the establishment of justice through covenants and its continuity in the language through the prolepsis of what is just, they saw a finding that offered man the required security to satisfy his necessary natural desires and his survival.
A fallacy in Plato's republic
R ECENT writers on the Republic tend to refrain from detailed discussion of the argument about justice and happiness, the main argument of the work.1 In the last decades there have been few assessments of Plato's conclusions about the relationship of justice and happiness, namely that just men are happier than any men who are unjust, and that the more unjust a man is, the more wretched he will be. Equally rare have been attempts to examine critically the argument by which Plato reached those conclusions.2 In this paper I make such an attempt. My aim is to show that Plato's conclusions are irrelevant to what he sets out-and purports-to establish. The fallacy of irrelevance that, in my judgment, wrecks the Republic's main argument is due to the lack of connection between two conceptions of justice that Plato employs. I begin with an account of the two conceptions. While discussing them, I try to correct some errors and possible confusions about Plato's argument and his understanding of it. In particular, I try to show that Plato consistently viewed his defense of justice as one made solely in terms of justice's effects. I then examine the fallacy in detail. At the end, I briefly speculate about why Plato proceeded as he did.
Metabolism of individual fatty acids by sheep depot adipose tissue in vivo and in vitro.
1. 
1. Sheep adipose tissue and plasma have high stearate and low unsaturated fatty acid content compared to rat, dog and man. 
 
2. 
2. In control animals in vivo uptake as well as release of various fatty acids by adipose tissue could be demonstrated. In vitro net release occurred. Fasting resulted in a decrease in tissue stearate and increased release of fatty acids. Adrenaline and noradrenaline had minimal lipolytic effect in vivo and in vitro. 
 
3. 
3. Variations in the turnover rate of individual fatty acids were observed.
