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

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