"Our only weapons in this war of your lifetime are the weapons of the mind"

In this quote, Paul Tsongas is emphasizing the power of the mind in the middle of a war. He recommends that in the existing war, which is most likely the one occurring during the reader's life time, the only weapons we have at our disposal are those of the mind. This might imply that physical weapons and brute force are not enough to win this war, which it is our intelligence, imagination, and vital thinking skills that will eventually lead us to victory. Tsongas is highlighting the value of utilizing our minds to plan and outsmart the opponent, rather than relying solely on physical force. This quote serves as a suggestion that the mind is a powerful tool that ought to not be undervalued in times of dispute.
