The propositions listed describe various cognitive processes and their relationships to one another, particularly in the context of encoding, decoding, and recoding information.

Manipulating facilitates encoding and decoding, which means that actively engaging with information can help to strengthen memory for that information. When we manipulate information, we are actively processing it in a way that helps to create a more robust memory representation. This can involve physically manipulating objects or mentally manipulating information by comparing, contrasting, or elaborating on it.

Non-linear encoding is a type of encoding that involves organizing information in a non-sequential manner. This can be contrasted with linear encoding, which involves organizing information in a sequential or ordered manner. Manipulating is necessary for non-linear encoding, as it allows us to create connections between different pieces of information and to see how they relate to one another in a non-sequential way. Scanning navigates non-linear encoding, as it allows us to quickly move through and survey the different pieces of information in a non-linear fashion.

Linear encoding is a type of encoding that is also a type of non-linear encoding. This may seem contradictory, but it reflects the idea that linear encoding is a simpler form of non-linear encoding. In linear encoding, information is still organized in a non-sequential manner, but the connections between pieces of information are more straightforward and easier to follow.
These propositions appear to describe the processes involved in encoding, decoding, and navigating information, particularly in the context of non-linear encoding. 

At the heart of these propositions is the idea that manipulating information facilitates various stages of the encoding process, including encoding itself, precoding, and recoding. This suggests that actively working with information, rather than simply passively receiving it, is essential for effective encoding. Additionally, decoding is also an active process that feeds into encoding, implying that the two processes are interconnected and inform one another. 

The propositions also highlight the importance of non-linear encoding, which is a type of encoding that does not follow a straightforward, sequential approach. Scanning and skimming are presented as strategies that support each other and facilitate navigation of non-linear encoding. Skimming, in particular, is seen as a way to develop a mental map of non-linear encoding, which is essential for effective information processing. 

Finally, the propositions suggest that linear encoding is a type of encoding that is related to non-linear encoding, and that both are part of a broader encoding process. Overall, these propositions describe a complex, dynamic process of information encoding and decoding that involves active manipulation, navigation, and interconnected stages.
