摘要
什么是虚概念？虚概念究竟有无内涵和外延？学界看法不一。逻辑学界对此主要有三种看法：虚概念有内涵有外延，有内涵无外延，无内涵无外延。试图从新的角度，即从“可能世界”的角度探讨虚概念的内涵和外延情况，并得出“现实世界的虚概念无内涵无外延；其他可能世界的虚概念或者有内涵有外延，或者无内涵无外延”的结论。
What is an empty concept Does an empty concept have any intension and extension？ The researchers in logical field have some different opinions, mainly three views as follow that an empty concept has both intension and extension, an empty concept has intension but no extension, and an empty concept has neither intension nor extension. The author tried to explore the situation of an empty concept＇ s intension and extension depending on the point of possible world, what it was from a new angle of view. And then we drew the following conclusions that an empty concept has neither intension nor extension in the real world, and an empty concept has both intension and extension or it has neither intension nor extension in some other possible worlds.
