Perhaps you should try some spelling variations:
"philanthropists" » "philanthropos"
"philanthropistus" » "philanthropismus", "philanthropist", "philanthropicus"
"philanthropism" » "philanthropist", "philanthropinism", "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: (("philanthropists" OR "philanthropic") OR ("philanthropistus" OR "philanthropism")).
• Removing quotes may allow a broader search: (( philanthropists or philanthropic ) or ( philanthropistus or philanthropism )).
• Adding a wildcard symbol may retrieve word variants: (("philanthropists" or "philanthropic") or ("philanthropistus" or "philanthropism"))*.
