Locke , helvetius , and diderot believed that all men have an equal aptitude for genius , and that what some are able to effect , under the laws which regulate the operations of the intellect , must also be within the reach of others who , under like circumstances , apply themselves to like pursuits 洛克、爱尔维休和狄德罗都相信所有的人都有相同的天赋，并且相信在约束大智英才的活动的法则之下，有些人所能完成的，其他的人在相似的环境下，致力于相似的追求，也准是力所能及的。
