A No-Go Theorem for the Nonabelian Topological Mass Mechanism in Four Dimensions [PDF]
We prove that there is no power-counting renormalizable nonabelian generalization of the abelian topological mass mechanism in four dimensions. The argument is based on the technique of consistent deformations of the master equation developed by G ...

The $\rho$ parameter at three loops and elliptic integrals [PDF]
We describe the analytic calculation of the master integrals required to compute the two-mass three-loop corrections to the $\rho$ parameter. In particular, we present the calculation of the master integrals for which the corresponding differential ...

Davidsonian Causalism and Wittgensteinian Anti-Causalism: A Rapprochement [PDF]
A longstanding debate in the philosophy of action opposes causalists to anti-causalists. Causalists claim the authority of Davidson, who offered powerful arguments to the effect that intentional explanations must be causal explanations.

Quantum scalar field in quantum gravity: the propagator and Lorentz invariance in the spherically symmetric case [PDF]
We recently studied gravity coupled to a scalar field in spherical symmetry using loop quantum gravity techniques. Since there are local degrees of freedom one faces the "problem of dynamics". We attack it using the "uniform discretization technique". We

Master Integrals for Fermionic Contributions to Massless Three-Loop Form Factors [PDF]
In this letter we continue the calculation of master integrals for massless three-loop form factors by giving analytical results for those integrals which are relevant for the fermionic contributions proportional to N_F^2, N_F*N, and N_F/N.

In this essay a new model is presented as an attempt to operationalize the otherwise slightly abstract concept of ”suitable disturbances” (coined by Humberto Maturana), which is a central concept in systemic coaching.

Good News for Moral Error Theorists: A Master Argument Against Companions in Guilt Strategies
Moral error theories are often rejected by appeal to ‘companions in guilt’ arguments. The most popular form of companions in guilt argument takes epistemic reasons for belief as a ‘companion’ and proceeds by analogy. I show that this strategy fails.

Aristotle’s Unanswered Questions: Women and Slaves in Politics 1252a-1260b
Aristotle is more straightforward than his interpreters. A number of scholars have championed an Aristotle guided by pure inductive observation to reach a theory of the inferiority of women and slaves.
