When traveling together under such circumstances, you quickly get to know your traveling companions, discovering what kind of character they have and how high their ideals are. So when we want to understand someone we not only examine his external appearance, but his way of life as well. By observing his actions we can determine whether he is good or bad. We can compare ideologies in a similar way. There are many different ideologies and moral standards.
Scholars claim that it is impossible to determine which is right and which is wrong.
They say that each individual is free to determine his own standard of morality and no one can say whether his choice was good or bad, right or wrong. If we accept this premise, however, there can be no universal standard of goodness or morality. We must decide based on the result. In this way we can determine whether an ideology or moral conviction is right or wrong. Of course, the motivation is also important.
