Man's purpose is to serve all mankind, not to serve only one man while doing harm to others.
For a Christian, the love of one's motherland can be an obstacle to the love of one's neighbor.
Lost souls escape their loss of control in patriotism.
— Dr. Samuel Johnson
Patriotism is not a virtue. Sacrificing your life for an institution which embodies prejudice cannot be your duty.
People do many bad things for selfish reasons; they do worse things for their families. But they do the worst in the name of patriotism and they are made proud by these crimes: spying, unduly heavy tax collecting, sacrificing lives, and waging wars.
Loving your country and loving your family are both virtues that can become vices when they become overwhelming and damage your love for your neighbor.
