Authors' name in scshape with biblatex

In a bibliography, I'd like to have all authors' names in scshape - I mean even the initials. PLease, consider this code:

\documentclass[a4paper]{article}
\usepackage[T1]{fontenc}
\usepackage[utf8]{inputenc}
\usepackage[italian]{babel}
\usepackage{textcase}
\usepackage[babel,italian=guillemets]{csquotes}
\usepackage[style=philosophy-verbose,backend=biber,classical=true,%
firstinits=true,volnumformat=strings,volumeformat=romansc,sorting=nyt,%
indexing]{biblatex}
\DeclareFieldFormat[article,book,inbook,incollection]{author}%
{\textsc\MakeTextLowercase{#1}}
    \nocite{*}

\begin{filecontents*}{\jobname.bib}
@book{ bertelli:2012,
       author    = "Lucio Bertelli",
       title     = "Tra storia e utopia",
       publisher = "Edizioni dell'Orso",
       location  = "Alessandria",
       year      = "2012",
     }
\end{filecontents*}

\addbibresource{\jobname.bib}

\begin{document}
\printbibliography
\end{document}

Well, the string

    \DeclareFieldFormat[article,book,inbook,incollection]{author}%
    {\textsc\MakeTextLowercase{#1}}

does produce no result. So, what have I to do? Thanx!
