text: how is it that evidence makes some people see the truth, while it fails to be convincing for others? what makes them so stubborn and insensitive? is it the the strong attachment which ignorant people have for this life. mind you, it does-“attachment”- explain the motives behind this incomprehensible attitude. although they clearly see the truth, they follow their vain desires, since they know that they would otherwise have to abandon their ambitions and make earning the good pleasure of allah the basic purpose of their life. this is actually the last thing they want to do and accordingly they resist it by suppressing the “voice of their conscience.” these people adhere to the negative side of their soul: such behaviour is to the detriment of man, as explicitly stated in the following verse:  (i do not exculpate myself. the (human) soul is prone to evil, save his to whom my lord has shown mercy. my lord is forgiving and merciful). noble qura’an, (surah yusuf: 53)  do you think they have been misguided? this is the best question you have asked yet. congratulations. i'm really proud of you. it is exactly stubbornness and insensitivity that makes people unable to accept evidence when it's clearly presented to them. most of the time they refuse to even consider the evidence - however voluminous it is - because they have political and/or religious motivations for not doing so. another important factor is education. the ability to consider information and evidence in a rational way is an important part of a healthy education. those who don't receive it unfortunately fall prey to demagogues and people with a malicious desire to foment discord among people. we must not allow them to win.  the truth is out there for all those who choose to seek it.
