Is people's behavior determined by force not thier own choice?  The author considers that it is impossible to have no relationship with other people when one live in society, which couldn't avoid that we would be influenced by other people's determines and surrounding.  As a consequence, peopel's behavior isn't follow their heart, that is, people's behavior is determined largely by force.  Certainly, there are many factors could affect us to make a desicion, which is not our first choice, but that isn't represent that all choices were determined by force.  Sometimes, these foeces could help us to exclude some confused problems, even some of choices could help us to make a steadfast choice which was truly coincidence with our heartfeelings.
In commonplace, somthing that could affect people to make a decision can divide into external, internal. Internal factors include our personility, preference and tastes.  However, these factors aren't force like the author cited. On the other hand, the external factors include environment, other people's decision, opportunities, laws and responsibility.  Nevertheless, these forces aren't force us to do something that we disgust, in the contrast, some stupid options were expelled by these force, and the options weren't our real choice, even these force could help us to establish a steadfast faith to operate something.
Unfortunely, we couldn't fallow our heart all the time and forces couldn't help us get rid of some disturbing options all the time. Most of times, we have no choice but to take other people's feelings into account, otherwise, we would be aloof by all the people sooner or later.  If we were all in a team, and everyone ignored command, then this team would never complete their mission.  On the contury, if all of people comply leader's command, they would meet their goal, although some of people has to disregard their opinions. For instance, in a rowing competation, everyone wouldn't be a champion unless they abondon their bias.
In additition, we have to consider many factors but our own choice in life. Our hierarchy of considersion is first to our responsibility, next to environment, then to others feelings, and finally to our own preferance. If we discarded our responsibily, that is, everyone wouldn't take any responsibillity even if we do something wrong, then the whole society would trouble in a fiasco, withou any doubt.  For example, students wouldn't obtain knowledge sedently, which is a catastrophe to our country. In addition, employees wouldn't devote themselves into their carreer, which would led to the economy of one country would bankrupt.
Whereas, I'm not deny that we are constrainted by many kinds of force, becourse of our responsibilty, laws. Most of time, the responsibility and laws doesn't restraint common public at all,; we still could fallow our hearts,instead, they just to constraint some people who have trend to do criminal things. Such as one want to steal a treature, however, when the one considered consquence he faced, he or she might give up the idea.  So, our society could be more peaceful.
Although most of time we have no choic to give up our own preferance but to take other people's feelings into consideration, these force also could help us to make a more wittful choice and firm our decision. In a word, forces wouldn't force us to do somthing we disgust all the time, however, they also firm our faith.
