Capriciousness

We can't tolerate such capriciousness.

The exuberance of the style and its tricky capriciousness may be, and are, condemned by purists as in questionable taste; but as an outcome of national feeling, and as an example of original inventive ingenuity and patience, this and other notable specimens of the style, to which reference will be made later, are of the highest interest to the student, and a delight to the ordinary observer who can free himself from the straightlaced traditions of the schools.

To employ always the same witnesses, he would excite speculation, and expose himself to the imputation of fickleness or capriciousness.
