It all comes down basically to engaging with each other and not closing ourselves off. There's a quote by Tolstoy that I love –
A person, “has only to come into contact…with
people equally good and bad, of different denominations,
who condemn each other’s beliefs, to doubt of the truth
of the belief he professes himself.”
- and basically, I think that means the more we engage with people, particularly those from a different background, the broader our viewpoints, the more we can see and understand, and the more humble we become.
So, I think engaging with refugees ideally, and migrants and just different people around you, talking to them, becoming friends with them, is the single greatest thing you can do to open your mind because it ceases to be about ‘them’ and it becomes about ‘us’. We see them as one of us and part of us.
