“You and I, we are fighting each other but we are not really enemies. By doing so we are dividing our strength, and we shall never reach our goal. Maybe the final extremity will bring us together. Maybe.”

Variant: Simply, all what we did is that we avoided the country a big crisis and a battle between Egyptians. Beware, instead of Egyptians fighting each other, no, you can fight us, and we protect all. how many would fight us? but Egyptians fighting each other would be a big war we couldn't have had the ability to deal with.

No Compromise – No Political Trading (1899)
Context: We shall never go wrong if we do what is opposed to the interests of our enemy. On the other hand, we shall almost never go right if we do what our enemies applaud. Historical development is a continuous conflict, a conflict of interests, a conflict of races, a conflict of classes. And if friendship does not count even in ordinary business, how much less so in such a conflict. Good-naturedness and sentimentality have no place in politics. They have never won a victory, but have brought unnumbered defeats. Bluecher’s motto, “Always follow the cannon’s roar and throw yourself upon the enemy,” is the best rule also in.

"The Tucson Zoo", p. 9
The Medusa and the Snail: More Notes of a Biology Watcher (1979)
Context: We are endowed with genes which code out our reaction to beavers and otters, maybe our reaction to each other as well. We are stamped with stereotyped, unalterable patterns of response, ready to be released. And the behavior released in us, by such confrontations, is, essentially, a surprised affection. It is compulsory behavior and we can avoid it only by straining with the full power of our conscious minds, making up conscious excuses all the way. Left to ourselves, mechanistic and autonomic, we hanker for friends.

Presidency (1977–1981), Inaugural Address (1977)
Context: The world itself is now dominated by a new spirit. Peoples more numerous and more politically aware are craving and now demanding their place in the sun – not just for the benefit of their own physical condition, but for basic human rights.
The passion for freedom is on the rise. Tapping this new spirit, there can be no nobler nor more ambitious task for America to undertake on this day of a new beginning than to help shape a just and peaceful world that is truly humane.
We are a strong nation, and we will maintain strength so sufficient that it need not be proven in combat – a quiet strength based not merely on the size of an arsenal, but on the nobility of ideas.
We will be ever vigilant and never vulnerable, and we will fight our wars against poverty, ignorance, and injustice – for those are the enemies against which our forces can be honorably marshaled.
We are a purely idealistic Nation, but let no one confuse our idealism with weakness.
Because we are free we can never be indifferent to the fate of freedom elsewhere. Our moral sense dictates a clearcut preference for these societies which share with us an abiding respect for individual human rights. We do not seek to intimidate, but it is clear that a world which others can dominate with impunity would be inhospitable to decency and a threat to the well-being of all people.
