"But steel bars have never yet kept out a mob; it takes something a good deal stronger: human courage backed up by the consciousness of being right"

This quote by Ray Stannard Baker highlights the idea that physical barriers, such as steel bars, are not enough to avoid a determined group of people from accomplishing their objectives. Instead, it takes something far more effective - human nerve and the belief in one's own righteousness. This suggests that no matter how strong or impenetrable a barrier might appear, it can be overcome by people who are driven by a strong sense of conviction and bravery. It likewise stresses the value of standing up for what is right, even in the face of difficulty. Eventually, this quote functions as a suggestion that true strength lies within the human spirit, not in product items.
