Perhaps you should try some spelling variations:
"philanthropists" » "philanthropos"
"philanthropism" » "philanthropist", "philanthropinism", "philanthrophist"
"philanthropismus" » "philanthropistus", "philanthropinismus", "philanthrophistus", "philanthropicus", "philanthropisches", "philanthropist"

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