自由主义作为西方文明的价值产物 ,是否有其未曾注意的认知基础 ?怀疑论作为西方文明的认知结晶 ,是否有其难以料到的价值内涵 ?这两大似乎栖息于不同领域的“思维形态” ,是否具有某种深层次的内在联系 ?如果说自由主义的核心概念是“个人自由” ,那么 ,怀疑论的核心概念又是什么 ?“无知”与“知识”的关系是什么 ?怀疑论意义上的“无知”与对“无知”的否定性理解有什么不同 ?什么是“积极无知”与“消极无知” ?怀疑论的“积极无知”在什么意义上支撑着自由主义的“个体性”概念 ?由伯林所揭示的“积极自由”与“消极自由” ,与本文所说的“积极无知”与“消极无知”有怎样的关系 ?“积极无知”与“消极自由”在什么意义上的联系 ,使得怀疑论成为了自由主义的逻辑平台 ?本文拟回答上述问题 Whether liberalism as the value product of Western civilization has its cognitive foundation that has not been paid attention to?
