He who knows not and knows he knows not, he is a child, teach him;
He who knows not and knows not he knows not, he is a fool, avoid him;
He who knows and knows not he knows, he is asleep, awaken him;
He who knows and knows he knows, he is a wise, follow him.
Old Arabic Proverb
I’ve been currently reading a book called The Mechanical Design Process, by David G. Ullman, in order to complete a project report of a course that I failed when I studied abroad last year. The book is full of really interesting details about design process and therefore I could recommend to those who are interested in design and its process.
Except interesting details about design process, the book also contains dozens of proverb related. It’s a kind of weird to imagine a book of engineering, particularly mechanical engineering, with so many proverbs in it. However, most of them I have read so far are related to subjects in the book.
The old Arabic proverb above is one of those proverbs in book, which impressed me rather than rest. Therefore, I thought it’d be better to share it with you. So, here it is.
