Rethinking Greed

In this paper I attempt to clarify the nature of the vice of greed, focusing on what can be called “modest greed”. Agents who are modestly greedy do not long for material goods or wealth with intense desires. Rather, they have quite modest desires, but ones whose satisfaction they pursue excessively relative to other goods. Greed - including modest greed - emerges as a particularly troubling and problematic vice

On Complacency

This paper begins by drawing attention to inadequacies in common characterizations of the vice of complacency. An alternative account is presented that avoids these flaws. The distinctive nature of complacency is then clarified by contrasting it with related vices, including apathy, resignation, akrasia, excessive pride, and hypocrisy

Autonomy, agency, and the value of enduring beliefs

My central thesis is that philosophers considering questions of epistemic value ought to devote greater attention to the enduring nature of beliefs. I begin by arguing that a commonly drawn analogy between beliefs and actions is flawed in important respects, and that a better, more fruitful analogue for belief would be desire, or a similarly enduring state of an agent. With this in hand, I argue that treating beliefs as enduring, constitutive states of agents allows us to capture the importance of accessible, justified, and true beliefs to sustaining personal identity, autonomy, self-control, and authenticity. We thus arrive at a significant value to such beliefs through their crucial role in our personal, practical identities

In Defense of the Primacy of the Virtues

In this paper I respond to a set of basic objections often raised against those virtue theories in ethics which maintain that moral properties such rightness and goodness (and their corresponding concepts) are to be explained and understood in terms of the virtues or the virtuous. The objections all rest on a strongly-held intuition that the virtues (and the virtuous) simply must be derivative in some way from either right actions or good states of affairs. My goal is to articulate several distinct, though related, objections grounded in this intuition, and to argue that virtue ethicists have ample resources to respond to these worries. The explanatory primacy of the virtuous over the right or the good emerges as a distinct and viable position

Electron Electric Dipole Moment induced by Octet-Colored Scalars

An appended sector of two octet-colored scalars, each an electroweak doublet, is an interesting extension of the simple two Higgs doublet model motivated by the minimal flavor violation. Their rich CP violating interaction gives rise to a sizable electron electric dipole moment, besides the quark electric dipole moment via the two-loop contribution of Barr-Zee mechanism.Comment: 8 pages, 2 figure

SO(10) SUSY GUT for Fermion Masses : Lepton Flavor and CP Violation

We discuss the results of a global $\chi^2$ analysis of a simple SO(10) SUSY GUT with $D_3$ family symmetry and low energy R parity. The model describes fermion mass matrices with 14 parameters and gives excellent fits to 20 observable masses and mixing angles in both quark and lepton sectors, giving 6 predictions. Bi-large neutrino mixing is obtained with hierarchical quark and lepton Yukawa matrices; thus avoiding the possibility of large lepton flavor violation. The model naturally predicts small 1-3 neutrino mixing, with $\sin \theta_{13} \simeq 0.05 - 0.06$. In this paper we evaluate the predictions for the lepton flavor violating processes, $\mu \to e \gamma$, $\tau \to \mu \gamma$ and $\tau \to e \gamma$ and also the electric dipole moment of the electron, $d_e$, muon and tau, assuming universal squark and slepton masses, $m_{16}$, and a universal soft SUSY breaking A parameter, $A_0$, at the GUT scale. We find $Br(\mu \to e \gamma)$ is naturally below present bounds, but may be observable by MEG. Similarly, $d_e$ is below present bounds; but is within the range of future experiments. We also give predictions for the light Higgs mass (using FeynHiggs). We find an upper bound given by $m_h \leq 127$ GeV, with an estimated $\pm 3$ GeV theoretical uncertainty. Finally we present predictions for SUSY particle masses in the favored region of parameter space.Comment: 25 pages, 18 figures, several typos in captions of tables 2 and 3 corrected, acknowledgments adde

The Minimal Model for Dark Matter and Unification

Gauge coupling unification and the success of TeV-scale weakly interacting dark matter are usually taken as evidence of low energy supersymmetry (SUSY). However, if we assume that the tuning of the higgs can be explained in some unnatural way, from environmental considerations for example, SUSY is no longer a necessary component of any Beyond the Standard Model theory. In this paper we study the minimal model with a dark matter candidate and gauge coupling unification. This consists of the SM plus fermions with the quantum numbers of SUSY higgsinos, and a singlet. It predicts thermal dark matter with a mass that can range from 100 GeV to around 2 TeV and generically gives rise to an electric dipole moment that is just beyond current experimental limits, with a large portion of its allowed parameter space accessible to next generation EDM and direct detection experiments. We study precision unification in this model by embedding it in a 5-D orbifold GUT where certain large threshold corrections are calculable, achieving gauge coupling and b-tau unification, and predicting a rate of proton decay just beyond current limits.Comment: 20 pages, 10 figures. v2: Minor typos and Reference errors corrected.
