“The opposite of every truth is just as true.”

“There are trivial truths and there are great truths. The opposite of a trivial truth is plainly false. The opposite of a great truth is also true.”

“A truth is not necessary, because we negatively are not able to conceive the actual existence of the opposite thereof;but a truth is necessary when we positively are able to apprehend that the negation thereof includes an inevitable contradiction. It is not that that we can see how the opposite comes to be true, but it is that the opposite can not possibly be true.”

“You can recognize a small truth because its opposite is a falsehood. The opposite of a great truth is another truth.”

“with every action theres an equal opposite reaction. With every problem, there’s a solution: just a matter of taking action.”

“True enough and opposites don't just attract they freaking catch fire and burn the entire city down.”
