A famous proposition put forward by Italian scholar Croce in 19 17. "All history is contemporary history" is a sentence widely quoted by Croce. But if this is interpreted as distorting history to cater to the present, then history is based on the present real life, that is to say, the past can only be understood if it coincides with the present horizon. It means that not only our thoughts are current, but our so-called history only exists in our present; Without the present life, there is no past history.
