Quotes by Thales

Many words are not proof of the wise man, because the sage only talk when it’s needed, and the words are measured and corresponding with the need.

We live not, in reality, on the summit of a solid earth but at the bottom of an ocean of air.

What is it that is most beautiful? - The Universe; for it is the work of God. What is most powerful? - Necessity; because it triumphs over all things. What is most difficult? - To know one's self. What is most easy? - To give advice. What method must we take to lead a good life? - To do nothing we would condemn in others. What is necessary to happiness? - A sound body and a contented mind.

Who is happy? This is a person, who has a healthy body, is dowered with peace of mind and cultivates his talents.
