there are 'No Tits from Is' i.e.
no things-in-themselves [tits] from is.
For Hume whatever is real and empirical matter-of-fact is confined to whatever is experienced.
Whatever is 'ought to' and things-in-themselves [thing-in-itself, noumenon] are rationalized from impressions and sensations via the memory and imagination. They are no real empirical matter-of-fact.
Those [PH and likes] who claimed their matter-of-facts or fact as a feature of reality that is just-is, being-so, that is/are the case, states of affairs, and the like are inferring the existing of things that are beyond the empirical experiences. Such inferences are grounded on an illusion.
Hume central Principle is this;
https://iep.utm.edu/hume/#H2
- All PERCEPTIONS are derived from the following
A. Impressions
-1. Of sensation (external) - external world, Unknown causes
-2. Of reflection (internal) – From Ideas [..B] in a certain way
B. Ideas – from Impressions [..A]
-1. From memory
-2. From imagination
---a. From fancy
---b. From Understanding
-----(1) Involving relations of ideas
-----(2) Involving matters of fact
As such, Hume's matter-of-fact cannot be,
"matter-of-facts or fact as a feature of reality that is just-is, being-so, that is/are the case, states of affairs, and the like" as claimed by PH and philosophical realists.
Hume's Matters of Fact is Unique

There is no room for Hume's matter-of-fact to be anything else other than the above "is".
Don't even try this 'unknown causes';
-1. Of sensation (external) - external world, Unknown causes
Point is 'sensation' is qualified to the human conditions thus cannot be absolute independent of the human conditions.
"Unknown causes' re Hume is limited to the extent of knowledge during Hume's time [1700s].
Hume stated he will leave it to the "anatomists* and philosophers' to find out what they are.
Now in the modern 2000s, the 'anatomists' referred to are those of the neurosciences and other advanced fields in science.
It is here, were we are still confined to Hume's "is" and enable objective moral facts within the human-based moral FSK with inputs from the modern 'anatomists' from the human-based science-biology FSK.
It is on this basis that there are objective moral facts and moral is objective as conditioned to the human-based moral FSK.
The above is a quick summary of Hume's philosophy, thus no references from Hume's Treatise or Enquiry. Can provide references where necessary.
