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

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