I believe it is the fourth phrase because it states that all races are like islands who need to be kind and have a friendship with eachother.
The third phrase where John Hume asks to respect the difference is the solution to cultural conflicts between the ethnic groups around the world.
Explanation:
In the first phrase, Hume tries to bring out the reasons for the conflict between the groups of people, while in the second phrase, he tells the world that, difference is nothing but an essence of humanity. In the fourth phrase, he urges the importance of two neighboring countries being friends rather than fighting each other.
Hence, the answer to our question lies in the third phrase.
