术数是中国传统文化重要和特殊的组成部分。作为一种认知现象，术数的起源和续存具有自然性，其基本的认知机制为：（1）基于心智知觉的朴素心身二元论；（2）具有进化优势的超敏感能动检测装置。从文化层面上说，术数认知的基本特征主要包括认知与评价相融合、认知与行动相统一和思维的关联性，相应地，功能上表现为实用而非求真。

Numerology (shushu)is an important and particular part of Chinese traditional culture. As a cognitive phenomenon,the origin and continuation of numerology is natural. According to the cognitive mechanism of numerology,it believes in a naive dualism of mind-body based on intellectual perception on the one hand,and a hypersensitive and active detection device with evolved advantages. At the cultural level,the fusion of cognition and evaluation,the unity of cognition and action,and the correlative thinking are three main features of numerology. Accordingly,numerology pursues practical effectivity rather than truth.
