"Speak softly and carry a big stick" (1901)
No hard and fast rule can be laid down as to where our legislation shall stop in interfering between man and man, between interest and interest. All that can be said is that it is highly undesirable on the one hand, to weaken individual initiative, and on the other hand, that in a constantly increasing number of cases we shall find it necessary in the future to shackle cunning as in the past we have shackled force.

• The vast individual and corporate fortunes, the vast combinations of capital which have marked the development of our industrial system, create new conditions, and necessitate a change from the old attitude of state and the nation toward property.

• Right here let me make as vigorous a plea as I know how in favor of saying nothing that we do not mean, and of acting without hesitation up to whatever we say. A good many of you are probably acquainted with the old proverb, “Speak softly and carry a big stick — you will go far.” If a man continually blusters, if he lacks civility, a big stick will not save him from trouble, and neither will speaking softly avail, if back of the softness there does not lie strength, power. In private life there are few beings more obnoxious than the man who is always loudly boasting, and if the boaster is not prepared to back up his words, his position becomes absolutely contemptible. So it is with the nation. It is both foolish and undignified to indulge in undue self-glorification, and, above all, in loose-tongued denunciation of other peoples. Whenever on any point we come in contact with a foreign power, I hope that we shall always strive to speak courteously and respectfully of that foreign power.

• Let us make it evident that we intend to do justice. Then let us make it equally evident that we will not tolerate injustice being done us in return. Let us further make it evident that we use no words which we are not which prepared to back up with deeds, and that while our speech is always moderate, we are ready and willing to make it good. Such an attitude will be the surest possible guarantee of that self-respecting peace, the attainment of which is and must ever be the prime aim of a self-governing people.

"Speak softly and carry a big stick" applies in many areas:

• foreign affairs
• domestic affairs 
• law & order
• politics
• business
• organized religion
