The wise are always impatient, for he that increases knowledge increase impatience of folly.

這句話中的兩個increase，為何第一個用的是increases,?第二個用的是increase？假如第一個increases是名詞的話，那應該在knowledge前面加上in

假如第一個increases是謂語的話，第二個increase也應該用謂語單數形式啊

The wise are always impatient, for he that increases knowledge increases impatience of folly.

that increases knowledge 是 he 的定語從句（格言中代詞可以跟定語從句），主句肯定是漏掉了單三形式的-s。
