Can we think without using language?

..."Research like Fedorenko's, Hurlburt's and others show that language is not essential for human cognition, which is a particularly important finding for understanding certain neurological conditions, such as aphasia. "You can kind of take away the language system, and a lot of the reasoning can proceed just fine," Fedorenko said. However, "that's not to say that it wouldn't be easier with language," she noted."
