Four Noble Truths contradicting? I don't even like to post a question like this but I just want to share a misconception that people from other beliefs have regarding Buddhism. Please what this video https://www.youtube.com/watch?v=c0ws36pd-Q0. 

 What this person says is that according to the third noble truth sorrow can be eliminated by getting rid of desire. And when desire is eliminated there is no reason to have a fourth noble truth which talks about the 8 fold path. This is just absolute illogical and misleading statements. But I just do not have the proper knowledge to make my Muslim friends understand why this is wrong. Please do share your views. Thank you
If you compare suffering to a sickness, the first noble truth would be knowing that you are sick. The second noble truth would be knowing the cause of the sickness. The third noble truth would be knowing that the sickness can be cured or knowing that there's a healthy state. The fourth noble truth would be knowing how to cure it or knowing how to reach that healthy state.
