<span>One symbol that is used in "To William Lloyd Garrison" is the presence of gloomy or foggy sentiments versus bright and light sentiments. This symbol is used to convey Whittier's message by putting us in the position where we feel anxiety during the 'dark' or gloomy moments, which is a natural feeling for a human being to have. The impact that this has on the poem as a whole is that it gives this underlying feeling of fear and danger that goes along well with his other themes of brotherhood and companionship.</span>
