No.

However, historically it was a verb, and could be used like "please to help me" as a command, or "if you please" (which is still possible today, but very formal) as in French s'il vous plaît.

Today, it's only used as a politeness marker in commands: "please [verb]", as in "Please help!", etc.

There is also a verb "please", meaning "to make someone enjoy something". That participle/adjective "pleased" is often used to describe what you are asking: "He or she was pleased by that". So yes, in a sense you can use it as a verb like that, but a little differently.

Also, the inverse of "the book pleases me" (which is a little unusual to say, though possible) would be "I enjoy the book" (or more casually just "I like the book").

The best way to say your sentence is probably "He or she enjoyed that".

However, historically it was a verb, and could be used like "please to help me" as a command, or "if you please" (which is still possible today, but very formal) as in French s'il vous plaît.

Similarly, "will/would/can/could you please do X". (Should "please" still be regarded as a verb in such instances?)

Also, this verb survives in sentences such as "I do as I please" and "You can do what you please".

I suppose that the transitive ("it pleases me") sense was detransitivized (e.g., middle voice?) as in "I please [myself]", and that usage has mostly disappeared except for some idioms (like you gave) and the later grammaticalization as a politeness marker/adverb.

Thanks.

I would have thought that the meaning in "I do as I please" is closer to the old "please to help me" than to "the book pleases me". The first two have the idea of "be pleased to", "be willing to", "wish", whereas the third has quite a distinct meaning, i.e. "give pleasure to".
