So, though there is inevitably selection in the writing of even the most private of diaries, the selection is of a different kind from that employed when the diary is to be published, or when it is thought of as designed perhaps for one other, an extended conversation or letter.

So, though there is inevitably selection in the writing of even the most private of diaries, the selection is of a different kind from that employed when the diary is to be published, or when it is thought of as designed perhaps for one other, an extended conversation or letter.
（だから，どんなに私的な日記を書くとぎでも必ず選択をせざるを得ないとは言え，その際に行われる選択は，その日記が出版されることになっていたり，あるいは他人に見せることを意図して書かれている場合，つまりは会話とか手紙の延長上として考えられている場合に行われる選択とは種類が異なるのである。）
