Definitely, mere similarity usually exclude the distinctive characteristics of a thing. We need to investigate its own terms for deeper understanding. Within the rough outline sketched by similarity, a more detailed and well-articulated picture can be drawn by grasping own terms of a thing. Still take window as an example. From careful observation, we know that it is transparent, it consists of different chemical materials, it performs the function as to protect privacy, to preserve desirable temperature indoor, and sometimes to prevent rains and snows from going inside. Deeper and further understanding of window can only be gained when we take its own terms besides those it shares with bookcase into consideration.
In the newly development software engineering model named Object-oriented model,the strategy “similarity first and differences later” functions as the core and focus of the whole model. Objects sharing common points are put into same “classes” and common points are processed together, later they are defined, discussed and processed respectively according to their own characteristics. This method greatly reduces the repetive time and energy spent over and over again on similar, if not utterly same, terms. Translated into daily life, starting from similarites for a quick outline and transferring to grasp distinctive characteristics for deeper understanding isthe approach we should always bear in mind when hoping to understand a thing with effectiveness and efficiency.
