人類生活在時間的長河之中，當下的所作所為不僅預示著未來，而且是過去之延續。如果你刻意忽視從前、迴避過去、或者詆毀歷史，則你正在障礙自己採取明智的行動。

Human life is lived in time-depth; present action takes place not merely in anticipation of the future but in the light of the past.  If you deliberately ignore, think away, or deface the past, you’re hampering yourself for taking intelligent action in the present.
