Perhaps you should try some spelling variations:
"philanthropism" » "philanthropinism", "philanthropismus", "philanthropists"
"philanthropist" » "philanthropists", "philanthropic", "philanthropos"
"philanthrophist" » "philanthropists", "philantropist", "philanthropic"

You may be able to get more results by adjusting your search query.

• If you are trying to use Boolean operators, they must be ALL CAPS: (("philanthropism" OR "philanthropist") OR "philanthrophist").
• Removing quotes may allow a broader search: (( philanthropism or philanthropist ) or philanthrophist ).
• Adding a wildcard symbol may retrieve word variants: (("philanthropism" or "philanthropist") or "philanthrophist")*.
