How can I replace "trans. by" with just "trans." in biblatex-philosophy?
Here's the format I need:

I'm most of the way there with the following:
documentclass[11pt, a4paper]{scrartcl}
% Bibliography preamble
\usepackage[giveninits=true, style=philosophy-modern]{biblatex}
\addbibresource{testbib.bib}
% Some tweaks I've already made
\DeclareFieldFormat{postnote}{#1}% no postnote prefix in "normal" citation commands
\DeclareFieldFormat{multipostnote}{#1}% no postnote prefix in "multicite" commands
\DeclareFieldFormat{pages}{#1}% no prefix for the `pages` field in the bibliography
\DeclareFieldFormat[article]{title}{#1} % Remove quotations from Article title
\setlength{\yeartitle}{5.4em} % Set greater spacing between the year and the title
\setlength{\postnamesep}{2.5ex plus 2pt minus 1pt}
\begin{document}
Sentence containing citation \parencite{pavese1965}.
\printbibliography
\end{document}
and .bib file:
@book{pavese1965,
Author = {Pavese, Cesare},
Publisher = {University of Michigan Press},
Title = {Dialogues with Leucò},
date = {1965},
Editor = {William Arrowsmith and D. S. Carne-Ross},
editortype = {translator},
Location = {Ann Arbor}}
Which outputs:

Any help with removing that single pesky word would be greatly appreciated.
