“Our party has a mass character, and hundreds of thousands of member. Owing to the situation in our country the bulk of Party members spring from the petty bourgeoisie. There is nothing surprising in it. IN the beginning under the influence of bourgeois ideology the stand of some Party members may lack firmness, their outlook may be confused and their thinking not quite correct, but owing to the fact that they have been tempered in the revolution and the war of resistance, our Party members are by and large good militants, faithful to the Party and the revolution. Those Comrades know that those Party members who commit errors will lead the masses into error; therefore, they stand ready to correct any mistake they may make, and this in a timely way, and do not allow small errors accumulate into big ones. They sincerely practice criticism and self-criticism, which makes it possible for them to progress together.”

Context: The future lies between hon. Members opposite and ourselves. We are not afraid on this side of the House of social reform. Members of our party were fighting for the working classes when Members or the ancestors of Members opposite were shackled with laissez faire. Disraeli was advocating combination among agricultural labourers years before the agricultural labourer had the vote, and when he first began to preach the necessity of sanitation in the crowded centres of this country, the Liberal party called it a "policy of sewage." We stand on three basic principles, as we have done for two generations past—the maintenance of the institutions of our country, the preservation and the development of our Empire, and the improvement of the conditions of our own people; and we adapt those principles to the changing needs of each generation. Do my Friends behind me look like a beaten army? We shall be ready to take up the challenge from any party whenever it be issued, wherever it is issued and by whomsoever it be thrown down.

This contains probably her most famous statement: Freiheit ist immer Freiheit der Andersdenkenden, translated as "Freedom is always the freedom of dissenters."
Variant: Freedom is always and exclusively freedom for the one who thinks differently.
Context: Freedom only for the members of the government, only for the members of the Party — though they are quite numerous — is no freedom at all. Freedom is always the freedom of dissenters. The essence of political freedom depends not on the fanatics of 'justice', but rather on all the invigorating, beneficial, and detergent effects of dissenters. If 'freedom' becomes 'privilege', the workings of political freedom are broken.
