Memory is information. Information has sense. Sense is only included in the future. Different senses cause different futures.
The past is one. Futures are many. Every possible branch of the future is defined by the conscious selection of an organism. The conscious selection of the organism is defined by its prediction of the future, and this prediction is the sense of the information.
Hence the past and the future are linked through the prediction of organisms, the sense of information which forms the organism's memory.
An active agent, organism, submerged into the environment possesses information about the environment forming its memory. Since no organism is programmed by a (or the) creator, that information is the only product of the environment allowing us to distinguish the organism from the environment.
To me, the separation between the past and the future, and between the organism and the environment is only a perceptional effect. In reality it is just one entity like one building viewed from different angles.
