The human condition that Baraka speaks about could be described as real emotions and feelings that are created by all human beings.
The train in the play could be seen as a paradigm to the Dutchman, which was a ship that transported African slaves. Both are types of transportation of people from one place to another. Though not in chains and shackles, the black man could still be considered a slave being transported on the train to a place to work. Having a story take place on a moving environment can be more effective since it shows the that time is always moving and could be interpreted as life, which is always moving and stops for no one.
The human condition can be understood in a better way by legitimate emotional resources that cannot be produced by evading these resources.
I believe these "legitimate emotional resources of the soul" are real emotions that are partially created by culture, society, and the overall environment we are brought up in, described as "resources."
While I do agree with Baraka in the idea that the human condition is of real emotions that we as humans feel. I believe that that these emotions and feelings of the human condition are felt universally by any person on Earth, and that "resources" are not a necessary part of the human condition.
