Speech, truth and liberty: Bentham to John Stuart Mill

Bentham’s Utilitarianism transforms earlier free speech doctrine in the service of the pursuit of truth and the control of government, preserving the distinction between statements of opinion and of fact and awarding the latter a lesser degree of protection. The work of James Mill and the early writings of John Stuart Mill retain this distinction, but their accounts are weighed down by the problems of a direct Utilitarian approach, in their consequentialist balancing of different values against each other, and in their dependence on a majoritarian epistemology and their commitment to a naive progressive optimism. Mill goes on in On Liberty to address and resolve these problems on the basis of a new justification for free speech as free deliberative thought. I argue that, contrary to most interpretations, his new justification leaves untouched the basic distinction between absolutely protected expressions of opinion and only functionally and contingently protected assertions of fact, leaving room for restrictions on factual statements, especially when untrue

Bentham, Not Epicurus: The Relevance of Pleasure to Studies of Drug-Involved Pain

There is a disproportionate focus on pain over pleasure in policy-relevant research on drugs. This is unfortunate because theories of and findings on drug-involved pleasure can be used to inform knowledge of drug-involved pain. The cross-fertilization of theories and findings is bolstered by the availability of a conceptual framework that links drug-involved pain and pleasure in a comprehensive, powerful, simple, and instrumental manner. This article proposes such a framework. It consists of four types of drug-involved pain and pleasure: drug-specific corporal; drug-related corporal; economic; and, social. This quaternary scheme is illustrated with findings from four literatures, namely those on methamphetamine use; alcohol-related sexual contact among college students; resource transfer among drug users and dealers; and, relational and communal issues related to drugs. The article concludes with implications for the field

Interferon inducible X-linked gene CXorf21 may contribute to sexual dimorphism in Systemic Lupus Erythematosus.

Systemic lupus erythematosus (SLE) is an autoimmune disease, characterised by increased expression of type I interferon (IFN)-regulated genes and a striking sex imbalance towards females. Through combined genetic, in silico, in vitro, and ex vivo approaches, we define CXorf21, a gene of hitherto unknown function, which escapes X-chromosome inactivation, as a candidate underlying the Xp21.2 SLE association. We demonstrate that CXorf21 is an IFN-response gene and that the sexual dimorphism in expression is magnified by immunological challenge. Fine-mapping reveals a single haplotype as a potential causal cis-eQTL for CXorf21. We propose that expression is amplified through modification of promoter and 3'-UTR chromatin interactions. Finally, we show that the CXORF21 protein colocalises with TLR7, a pathway implicated in SLE pathogenesis. Our study reveals modulation in gene expression affected by the combination of two hallmarks of SLE: CXorf21 expression increases in a both an IFN-inducible and sex-specific manner
