very good question - at the end - trust is something independent of a person - maybe the saying ' we trust in god ' has some truth - however - I strongly believe is that we need to nourish trust in each other (there is a beautiful youtube which is a social experiment also which exactly underlines what I try to stress) - the problem is that we need to enhance a culture of humanity ......in a new way ....(given that other ethical systems vanish more and more..... )
