Why does 'thoughts' and 'memories' not part of aggregates? In MN:44 it is said,

Visākha, the Buddha said that these five grasping aggregates are
identity. That is: form, feeling, perception, choices, and
consciousness. The Buddha said that these five grasping aggregates are
identity.”

If feelings are included in identity forming aggregates why 'thoughts' and 'memories' are not included. Afterall, what I think, like, what I feel, makes my self-identity. To quote Rene Decartus, 'I think therefore I am'. Isn't the constant chattering of mind generate a sense of self.
Also, memory of things I did have a powerful effect on sense of self.
So, why not included them?
It's all included, it's just a slightly different structure.
Latent memories just sitting there are included in &quot;samskara&quot; (what's incorrectly translated as &quot;choices&quot; in your copy).
Active memories you are going over now are included either in &quot;perception&quot; (as associations to whatever you perceive)
Or in &quot;form&quot; if, for example, you are visualizing a piece of memory, creating forms in front of your mind's eye.
The way mental stuff is organized in Buddhism is a bit more technical than in our civilization. So instead of calling bunch of different things &quot;thoughts&quot;, Buddhism gets more specific and classifies things according to how they work.
Thinking is going through a chain of associations, so each thought is a (mental) form, then it goes through perception (supported by latent memories), which finds next association, which then becomes the new form etc.
