  Dennis Hackethal commented on idea #5088.

Is rejecting an idea equivalent to adopting it's negation?

Logically, yes. But in practice, it won’t be the same.

For example:

Idea A: ‘Newtonian gravity is true.’ → Has pending criticisms (some predictions don’t match observation).
Idea B: ‘Newtonian gravity is not true.’ → Also has pending criticisms: ‘Not helpful’; ‘Doesn’t tell us how gravity works’; etc.
