Self-love and self-liking in the moral and political philosophy of Bernard Mandeville and David Hume

This work offers a novel interpretation of David Hume’s (1711–1776) conception of the conjectural development of civil society and artificial moral institutions. It focuses on the social elements of Hume’s Treatise of human nature (1739–40) and the necessary connection between science of man and politeness, civilised monarchies, social distance and hierarchical structure of civil society. The study incorporates aspects of intellectual history, history of philosophy and book history. In order to understand David Hume’s thinking, the intellectual development of Bernard Mandeville (1670–1733) needs to be accounted for. When put into a historical perspective, the moral, political and social components of Treatise of human nature can be read in the context of a philosophical tradition, in which Mandeville plays a pivotal role. A distinctive character of Mandeville and Hume’s account of human nature and moral institutions was the introduction of a simple distinction between self-love and self-liking. The symmetric passions of self-interest and pride can only be controlled by the corresponding moral institutions. This is also the way in which we can say that moral institutions are drawn from human nature. In the case of self-love or self-interest, the corresponding moral institution is justice. Respectively, concerning self-liking or pride the moral institution is politeness. There is an explicit analogy between these moral institutions. If we do not understand this analogy, we do not understand the nature of either justice or politeness. The present work is divided into two parts. In the first part, ‘Intellectual development of Bernard Mandeville’, it is argued that the relevance of the paradigmatic change in Mandeville’s thinking has been missed. It draws a picture of Mandeville turning from the Hobbism of The Fable of the Bees to an original theory of civil society put forward in his later works. In order to make this change more apparent, Mandeville’s career and the publishing history of The Fable of the Bees are examined comprehensively. This interpretation, based partly on previously unknown sources, challenges F. B. Kaye’s influential decision to publish the two parts of The Fable of the Bees as a uniform work of two volumes. The main relevance, however, of the ‘Intellectual development of Mandeville’ is to function as the context for the young Hume. The second part of the work, ‘David Hume and Greatness of mind’, explores in philosophical detail the social theory of the Treatise and politics and the science of man in his Essays. This part will also reveal the relevance of Greatness of mind as a general concept for David Hume’s moral and political philosophy.

Effects of oxygen provision on the physiology of baker's yeast Saccharomyces cerevisiae

The availability of oxygen has a major effect on all organisms. The yeast Saccharomyces cerevisiae is able to adapt its metabolism for growth in different conditions of oxygen provision, and to grow even under complete lack of oxygen. Although the physiology of S. cerevisiae has mainly been studied under fully aerobic and anaerobic conditions, less is known of metabolism under oxygen-limited conditions and of the adaptation to changing conditions of oxygen provision. This study compared the physiology of S. cerevisiae in conditions of five levels of oxygen provision (0, 0.5, 1.0, 2.8 and 20.9% O2 in feed gas) by using measurements on metabolite, transcriptome and proteome levels. On the transcriptional level, the main differences were observed between the three level groups, 0, 0.5 2.8 and 20.9% O2 which led to fully fermentative, respiro-fermentative and fully respiratory modes of metabolism, respectively. However, proteome analysis suggested post-transcriptional regulation at the level of 0.5 O2. The analysis of metabolite and transcript levels of central carbon metabolism also suggested post-transcriptional regulation especially in glycolysis. Further, a global upregulation of genes related to respiratory pathways was observed in the oxygen-limited conditions and the same trend was seen in the proteome analysis and in the activities of enzymes of the TCA cycle. The responses of intracellular metabolites related to central carbon metabolism and transcriptional responses to change in oxygen availability were studied. As a response to sudden oxygen depletion, concentrations of the metabolites of central carbon metabolism responded faster than the corresponding levels of gene expression. In general, the genome-wide transcriptional responses to oxygen depletion were highly similar when two different initial conditions of oxygen provision (20.9 and 1.0% O2) were compared. The genes related to growth and cell proliferation were transiently downregulated whereas the genes related to protein degradation and phosphate uptake were transiently upregulated. In the cultures initially receiving 1.0% O2, a transient upregulation of genes related to fatty acid oxidation, peroxisomal biogenesis, response to oxidative stress and pentose phosphate pathway was observed. Additionally, this work analysed the effect of oxygen on transcription of genes belonging to the hexose transporter gene family. Although the specific glucose uptake rate was highest in fully anaerobic conditions, none of the hxt genes showed highest expression in anaerobic conditions. However, the expression of genes encoding the moderately low affinity transporters decreased with the decreasing oxygen level. Thus it was concluded that there is a relative increase in high affinity transport in anaerobic conditions supporting the high uptake rate.
