7.I continued this method some few years, but gradually left it, retaining only the habit of expressing myself in terms of modest diffidence; never using, when I advanced any thing that might possibly be disputed, the words certainly, undoubtedly, or any others that gave the air of positiveness to an opinion; but rather said, I conceive or apprehend a thing to be so and so; it appears to me, or I should not think it so or so, for such and such reasons; or I imagine it to be so; or it is so, if I am not mistaken.
我用这种方法已有好几年，但是慢慢地抛弃了，只保留有礼谦逊的语气和习惯；当我进行一件须辩驳的事情时，如「确实」「无疑」和其它字而产生一种意见执拗的神态者，这字我是绝不用的；只好说「我猜想，」或「恐怕这事是这样，」「我似乎以为，」或「因为这样的理由我想也许是如此的；」或者「我猜想这该是如此，」或「这是如此，如果不是我错误。」
