Quote by Marshall McLuhan
For tribal man space was the uncontrollable mystery. For technological man it is time that occupies the same role.
Summary
This quote implies that throughout history, the concept of "the unknown" has shifted from being associated with space to being associated with time. In the past, tribal societies viewed space as an incomprehensible and mysterious entity. However, in today's technological age, time has become the prominent source of uncertainty. This suggests that with the advancements of technology, humans have gained more control and comprehension over space, while the elusive nature of time remains perplexing and overwhelming.
