involuntary impulse

Really, just how passionate can you be about an involuntary impulse to put your hands up in the air?

Why does not our involuntary impulse always make the table turn?

Even then thinking I had said too much, especially as I by an involuntary impulse found my fingers compress her's, I added, "I plainly see the impropriety of asking you to renew your goodness—I must not be selfish, or urge you to take any step for which you may hereafter condemn yourself."

On a certain morning, after greeting Raimundo with the gesture peculiar to Spanish ladies, of opening and shutting her hand several times and going on her way, an involuntary impulse prompted her to look back once more at the corner window.

Nor can any one be surprised or scandalized, if I acknowledge my weakness in stating that I could not resist an involuntary impulse to laugh at them "in my sleeve."
