RT Article T1 Acting Under the Guise of the Bad - Editorial Introduction JF Ethical theory and moral practice VO 21 IS 1 SP 1 OP 3 A1 Hanisch, Christoph LA English PB Springer Science + Business Media B. V YR 2018 UL https://www.ixtheo.de/Record/1568627319 AB I introduce the topic of the Special Issue and highlight the central themes that the six contributors address in their essays. The moral-philosophical problem of the possibility of bad action is situated within the broader context of its action-theoretical significance, that is, as the most important challenge to the influential idea that an intentional action is necessarily performed under the guise of the good. J. David Velleman's discussion of the character of Milton's Satan is mentioned to illustrate the Special Issue's main question of whether instantiations of individual and collective agency are conceivable that deliberately act for the sake of the bad.
