Abstract：
What Babies Know outlines a compelling case for why infancy research is fundamental for conceptualizing what it is to be human. There is another period in human development that is relatively inaccessible, yet is more important. In order to truly understand the nature of core knowledge, perception, and cognition, we must start not with the infant, but with the fetus.
摘要：
婴儿知道什么概述了一个令人信服的案例，说明为什么婴儿期研究是概念化人类的基础。人类发展还有一个相对难以接近的时期，但更重要。为了真正理解核心知识的本质，感知，和认知，我们不能从婴儿开始，而是胎儿.
