HYPOTHESIS. “It is believed that first came verbal language and then mathematical thought. But I suggest otherwise. The origin of verbal language, the origin of the mind and the origin of mathematic thinking all happened at approximately the same time and that these three elements are basically interlinked. Human verbal language was as much a product of mathematical thinking as mathematics was a product of verbal language.”
