Globalization is a two-edged sword that extends Western knowledge everywhere but threatens the wisdoms of the Eastern world. According to McLuhan, the world needs a combination of both Western and Eastern knowledge. The West operates by way of visual space as a linear, quantitative mode of perception, while the East operates by way of acoustic space as a holistic, qualitative mode of perception. Because both worlds are constantly colliding, we need a mutual understanding in order to foster peace.
