You have to know the past to understand the present.

The habit of looking into the future and thinking that the whole meaning of the present lies in what it will bring forth is a pernicious one. There can be no value in the whole unless there is value in the parts.

The distinction between the past, present and future is only a stubbornly persistent illusion.

It is said that the present is pregnant with the future.

Everyman's life lies within the present for the past is spent and done with and the future is uncertain.
