'Tis. I'm pretty sure I learned it from Steven Black, who 'got' OOP
long before I did.
He, in turn, is likely to have picked it up from Eric Gamma, of the
Gang of Four:

It's a key idea behind object orientation: don't tell objects what
code to run, send a message to them telling them what result you're
after, and leave the implementation to the object (information
hiding).
One of the great benefits--as I used to preach at Central PA VFP Users
Group in my OOP sessions--was that the code was easily portable.
