Kokoro, by Natsume Soseki (paragraph #290)

斯ういふ過去を二人の間に通り拔けて來てゐるのですから、精神的に向上心のないものは馬鹿だといふ言葉は、Kに取つて痛いに違いなかつたのです。然し前にも云つた通り、私は此一言で、彼が折角積み上げた過去を蹴散らした積ではありません。却つてそれを今迄通り積み重ねて行かせやうとしたのです。それが道に達しやうが、天に屆かうが、私は構ひません。私はたゞKが急に生活の方向を轉換して、私の利害と衝突するのを恐れたのです。要するに私の言葉は單なる利己心の發現でした。

translation

Having passed through such a past between the two of them, it must have been painful for K to say that those who are mentally unimproved are idiots. However, as I said before, I am not the product of just throwing away the past that he has worked so hard to build up. On the contrary, I tried to keep it going as before. Whether it reaches the road, whether it reaches heaven, I don't care. I was simply afraid that K would suddenly change the direction of his life and conflict with my interests. In short, my words were the manifestation of mere selfishness.
