The wow thing that I have in this module is that I have some troubles in understanding the following sentence that “Observable behaviours are much more critical than the understanding of internal activities” as I can not figure out some examples in my daily life to support it. The wonder thing in this module is as follows: what is pragmatism? Could anyone use simple language to help me to have a better understanding of this term? Firstly, it is quite hard for me to have a good understanding of the term pragmatism on the basis of my previous knowledge. In addition, there are something that makes this term become quite abstract for understanding.
