Of course ideas matter and have consequences. The mistake is to
identify them with individual responsibility. Do you blame Newton
every time a vase falls off a shelf?
In hindsight, naming my cat Newton may have been a bad idea.
Newton is not responsible for gravity because he didn't create it.
Nevertheless, as an entity with mass Isaac Newton was complicit in contributing towards gravity’s tyrannical effects. In fact, his corpse continues to exert a gravitational pull to this day. /s
