Step-by-step explanation:
1984 is about a totalitarian society led by a ruthless dictator named Big Brother, who might be or might not be real.
In this totalitarian society, the lives of people are controlled in every possible way: from the moment they wake up, to the work they do, to the moment they go to bed. Even thoughts are controlled.
However, the majority of people are like drones of the system because they have been brainwashed by the state, and one of the brainwashing techniques that the state uses is "doublespeak". Doublespeak consists in using one word to say the opposite.
In the quote, we can see doublespeak clearly: "war is peace", "freedom is slavery", and "ignorance is strenght".
The totalitarian nations of this book are in perpetual war, but war brings peace according to the brainwashing. The people are slaves to the system, but they think they are actually "free". And they are also ignorant, but they believe that ignorance makes them "strong".
