I hope you guys all read the comments at the bottom of the article.
Assuming Hitler said this which I doubt because the word "private" wasn't in his vocabulary. It doesn't make any difference if he said it or not other then I would be surprised to see him say anything about individuality in any since of the word.
Hitler doesn't explain what the logical foundation is. Since Hitler was strongly against the individuals needs the foundation isn't hard to guess. and wanted to do away with private property as we know it today.
Was there something of interest in the comments?
