"When we come to images or memories or thoughts, speculation, while always closely related to practice, is more explicit, and it is in fact not immediately obvious that such processes can be described in any sense as practical"

This quote by Samuel Alexander suggests that when we think about images, memories, ideas, as well as speculation, the connection between technique and also conjecture is close, yet supposition is more specific. Alexander suggests that it is not immediately clear that these processes can be seen as useful. He is recommending that supposition is more abstract than practice, which it is challenging to describe these procedures as functional. Alexander is highlighting the significance of conjecture in recognizing pictures, memories, as well as thoughts, and how it is related to practice. He is recommending that conjecture is a fundamental part of recognizing these procedures, and that it needs to not be forgotten. Alexander is highlighting the significance of both practice as well as speculation in recognizing these processes, and exactly how they belong.
