Is it possible to go back in time and also avoid paradoxes?

If this is a theoretical question... physically going back in time is not an option, but it is possible to go back in time through history, literature, the mind (imagination). In terms of avoiding paradoxes... In literature: Paradoxes may be avoided if its existence wasn't acknowledged as a literary term. In everyday life: It can be avoided if it was a crime to use them. But you can never truly take away the existence of paradoxes because you can still think them. You can still think, "oh that's such a paradox" or "that's a jumbo shrimp".

add I think that the problems caused by paradoxes are sufficiently serious, that were time travel possible, then beings from the future would have erased it.
