The words of this old print read, in modern English: 'He over all the stars does reign That unto wisdom can attain'. In other words, 'Whoever can become wise will rule over everything.' Wisdom is knowing things that help a person to live sensibly and make good decisions. Wisdom is defined differently by many cultures. Some say that wisdom is something a person learns as they grow older. Other cultures expect people to complete certain rituals in order to get wisdom.
