I would be tempted to say yes the only way to knowledge is by science.
I did at first think of some exceptions to this but then changed my mind after thinking about it.
Even in music and poetry you have to first still play the notes or write the words and test and experiment what they sound like.
Even if you're talking about personal tastes about what you like or dislike you have to still decide if you like something by testing it.
Mathematical ideas have to be tested.
Even if you're studying English you only know as a person that what you're being taught is right when you test your English knowledge and you know other people are understanding it and you're communicating English effectively.
Since science is basically defined as the practice of acquiring knowledge you have to ask yourself what knowledge can you have without acquiring it.

Are you ready for the fire? We are firemen. WE ARE FIREMEN! The heat doesn’t bother us. We live in the heat. We train in the heat. It tells us that we’re ready, we’re at home, we’re where we’re supposed to be. Flames don’t intimidate us. What do we do? We control the flame. We control them. We move the flames where we want to. And then we extinguish them.
Impersonation is treason.
