Thankfully, "making my case" for a standard definition is not something I need to do.

It's very basic stuff.

If you are unable to work it out from the original link and description I gave or the previous reply, I think any more effort on my part will be a pointless time sink.

No, you do need to make your case--i.e. mount an argument based on evidence and reason--if you want me to believe "scientism" is real. That it has a "standard definition" is not enough. After all, you can look up in any dictionary the standard definitions for other things that are also not real, like clairvoyance, telekinesis, and palmistry. Until you or someone else does make a case, I'm going to continue believing scientism is little more than a cry from charlatans who lost the attention of their audience.
