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

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: (("philanthropists" OR ("philanthropist" OR "philanthropos")) OR "philanthropism").
• Removing quotes may allow a broader search: (( philanthropists or ( philanthropist or philanthropos )) or philanthropism ).
• Adding a wildcard symbol may retrieve word variants: (("philanthropists" or ("philanthropist" or "philanthropos")) or "philanthropism")*.
