The True Wise Man
No one should claim that whatever he has learned is concrete and barricade the doors to additional knowledge. He should keep his mind open for new words, new information, new knowledge, new arguments, and new notions; maybe the things he is about to witness will be much more worthy than what he already has in his mind.
I put this in simple terms: even a wise man and a scientist cannot claim that he knows everything, not even if the fame of his knowledge has conquered the horizons, because knowledge is as broad as the infinite universe. There is a saying that all people know all things, but one individual cannot know everything. So, assertions such as what I know is enough, or what I know is correct, or what I know is enough for me and I need no more, are all wrong. As stated in the Holy Quran: “So give good tidings to my servants who listen to speech and follow the best of it. Those are the ones Allah has guided, and those are people of understanding.” (Az-Zumar, Verses 17 and 18)
The “Bhagavad Gita,” a sacred book of Hinduism, states: “One who has faith, and one who is focused and diligent and devoted, he can acquire knowledge. Once he acquired knowledge, he will instantly reach ultimate serenity. With the sword of knowledge, tear down impure thoughts emerged in your mind by ignorance. Have faith and arise…”
The “Gospel of Luke,” section 3, states, “… and do not envision this thought that Abraham is your father, because I tell you that God can emerge children for Abraham from these stones.”
In the book “Xiaojing,” from Confucianism, it is said that: “Do not envision yourself so mighty that others look diminutive in your eyes.”
In the “Analects of Confucius,” it states: “a mighty man is glorious and without arrogance, and a diminutive man is arrogant without glory.
