The psalm of life , the tide rises , the tide falls 

Fairness and justice 

First i am going to show you an introduction of the valúes of fairness and justice and then i am going to tell you about My opinión of this valúes and Also i am going to tell of they are shown or presented in the story 

Fairness is the quality of making judgments that are free from discrimination.meaning "pleasing, attractive." This makes sense given that the word is also used to describe physical beauty.

Justice the quality of being just; righteousness, equitableness, or moral rightness: to uphold the justice of a cause. rightfulness or lawfulness, as of a claim or title; justness of ground or reason: to complain with justice.

To start in My opinión this values are presented in this poems ( a psalm of life and the tide rises, the tides falls) but then are presented in a very deep way in dime cases not in all the poem or in all the actions or expression of the author.

In a psalm of life as we can see in the first Stanza he is trying to show us that life is somenthing that has to happend in the way it is life is like an act of justice what you go is what latero is going to happend to you , Also he shown us that the death is somenthing that always is going to happend , the time is like a fairness , is somenthing that we can never forget it and is always going to pass , life is something that show you that you never end of learning or doing new things , so for that Reason i think that the author want all the readers to take or know the importance of the life of a person and Also that is really important to have fairness and justice 

In the tide rises , the tide falls , this poem is really deep and I think that the author Henry wadswoth Longfellow want to show us the way that de ocean and the world is , and the fairness and justice that this have , this values are not shown or presentd like as you read , you are going to find this values if you read in a very carefully and deep way , also you have to analyze it , in the part that he says The tide rises, the tide falls,  I think this is like and act of justice because all happend in the way that is has to occur also in the third stanza he says that The day returns, but nevermore I think that in this part he is trying to show as the message that we have to enjoy life with justice and fairness because it never comes back.
