Laravel 5.7 - Why does programmatically listing console commands return 0?

I'm currently trying to return the list of Artisan commands within my Laravel application. I tried running return var_dump(Artisan::('list')); with success, but my response was unexpected. It came back as int(0) or 0 when I took out the var_dump() function. When I run this same command in my console, it returns the list of artisan commands successfully.

Any thoughts on why this might be happening?
