Cultural conditioning

Daido Loori Roshi , one of my Zen teachers often made comments about the effect of cultural conditioning.  Today  in England we celebrate the feast day of St. George our patron saint  and it is also commemorated as the birthday and anniversary of the death of William Shakespeare.  So I am wondering what , if any , is the cultural conditioning that we have received through having these two figures in our heritage and hos will those be who perhaps live in Ireland with St. Patrick and James Joyce.  So is cultural conditioning all bad or has it some good to offer us?  What are the good and the bad bits?  When we sit Zazen therefore and we disassociate from the thoughts that run through us what place dies our cultural conditioning have and what do we make of that.  My answer just now is the ‘I don’t know’
