    This paper presents a novel Hegelian view of the relationship between aesthetics and democratic politics. My account avoids the drawbacks associated with approaches that (like Rancière’s) reconceive all of the political in aesthetic terms or (like Rockhill’s) reduce the aesthetic to art. Instead, I maintain that the aesthetic is best understood as a distinct relationship of individual freedom. My argument proceeds by highlighting shortcomings of Honneth’s account of democratic Sittlichkeit and then addressing these impasses by integrating aesthetic freedom into the picture. The first two steps of my argument concern the fact that the form of life outlined by Honneth aspires to be a form of free life, yet his account of democratic Sittlichkeit gives rise to two dimensions of unfreedom. The first problem of unfreedom pertains to the scope of freedom. The relationships of freedom incorporated into Honneth’s account fail to turn given social roles into the subject matter of a sufficiently unrestricted practice of freedom. The second problem of freedom concerns conformism. In a final step, I complete my argument that Honneth’s account is unsatisfactory and incomplete by showing that aesthetic freedom is socially valid and thus ought to form part of our accounts of democratic ethical life

    DNA from the human myeloid cell line HL-60 was cotransfected with the cloned thymidine kinase (tk) gene of herpes simplex virus into tk-deficient mouse L cells. tk-positive recipients expressing antigens detected on HL-60 cells were isolated with a fluorescence-activated cell sorter by use of a panel of monoclonal antibodies that detect epitopes on both normal and malignant myeloid cells. Independently sorted populations of transformed mouse cells showed concordant reactivities with four of the monoclonal antibodies in the panel (DU-HL60-4, MY7, MCS.2, and SJ-D1), which suggested that these antibodies reacted to products of a single human gene. A second round of DNA transfection and cell sorting was performed with donor DNA from primary transformants. Two different dominant selection systems were used to isolate secondary mouse L cell and NIH/3T3 cell transformants that coexpressed the same epitopes. Analysis of cellular DNA from secondary mouse cell subclones with a probe specific for human repetitive DNA sequences revealed a minimal human DNA complement containing a characteristic set of restriction fragments common to independently derived subclones. Two glycoproteins, of 130,000 (gp130) and 150,000 (gp150) mol wt, were specifically immunoprecipitated from metabolically labeled lysates of mouse cell transformants and were shown to contain [35S]methionine-labeled tryptic peptides identical to those of analogous glycoproteins expressed in the donor human myeloid cell line. Kinetic and biochemical analyses established that gp130 is a precursor that differs in its carbohydrate moiety from gp150, the mature form of the glycoprotein detected on the cell surface. The isolation of human gene sequences encoding gp150 in a mouse cell genetic background provides the possibility of molecularly cloning the gene and represents a general strategy for isolating human genes encoding differentiation-specific cell surface antigens

    DNA from a tertiary mouse cell transformant containing amplified human sequences encoding a human myeloid membrane glycoprotein, gp150, was used to construct a bacteriophage lambda library. A single recombinant phage containing 12 kilobases (kb) of human DNA was isolated, and molecular subclones were then used to isolate the complete gp150 gene from a human placental genomic DNA library. The intact gp150 gene, assembled from three recombinant phages, proved to be biologically active when transfected into NIH 3T3 cells. Molecular probes from the gp150 locus annealed with a 4.0-kb polyadenylated RNA transcript derived from human myeloid cell lines and from tertiary mouse cell transformants. The gp150 gene was assigned to human chromosome 15, and was subchromosomally localized to bands q25-26 by in situ hybridization. The chromosomal location of the gp150 gene coincides cytogenetically with the region assigned to the c-fes proto-oncogene, another human gene specifically expressed by myeloid cells
