Natural law is defined as a certain set of rules that humans inherit by nature, right reason or religion and are essential for all human conduct.
It states that there are some basic principles that humans must follow to go through life. Natural law also persuades the use of reason to analyze human nature and to deduce binding rules of moral behavior.
In a sentence, natural law states that every member of the society should be treated fairly and provided with justice and this important to maintain peace in a society.
Humans need to eat and drink in order to survive, therefore it against natural law to deprive oneself of food and water, as natural law says that species must survive.
I think that if people are well educated they tend to know better about the process, laws. Etc. Also, they can't be fooled very easily. Something along those lines.
Welcome to any place means you will be received with pleasure by anyone you pay a visit to. However, you will not feel glad or happy if you are welcome to a place you hate, but you have to go to or if you are welcome to hell. Take the song Welcome to the Jungle by Guns &Roses .How could you be welcome in a place with so much violence and death?
