Patriotism ruins history.

In history, truth should be held sacred, at whatever cost . . . especially against the narrow and futile patriotism, which, instead of pressing forward in pursuit of truth, takes pride in walking backwards to cover the slightest nakedness of our forefathers.

We all know that part of history. It indicates your patriotism, your perseverance and your character. The Chinese people are all grateful to you because you made outstanding contributions to our country's scientific and technological cause and national defense. ... Now, like in the 1950s, we are mapping out the development plan for a new round, and have set the key fields and key technologies, and also more than ten significant special programs.

He who cannot draw on three thousand years is living from hand to mouth.

Patriotism , as a feeling of exclusive love for one's own people, and as a doctrine of tile virtue of sacrificing one's tranquillity, one's property, and ever, one's life, in defence of one's own people from slaughter and outrage by their enemies, was the highest idea of the period when each nation considered it feasible and just, for its own advantage, to subject to slaughter and outrage the people of other nations.

Patriotism is supporting your country all the time and your government when it deserves it.
