"When quick results are imperative, the manipulation of the masses through symbols may be the only quick way of having a critical thing done"

John Grierson's quote suggests that when it is needed to achieve an objective rapidly, the most efficient method to do so may be to control the masses through signs. This suggests that symbols can be utilized to affect the public's opinion and habits in order to achieve a wanted outcome. This idea is particularly pertinent in today's world, where the power of symbols is often utilized to influence public opinion and shape public discourse. For instance, symbols such as flags, logos, and slogans are used to stimulate strong feelings and produce a sense of unity and belonging. By controling the masses through symbols, it is possible to rapidly achieve a desired result.
