question

For example, in Prince v. Massachusetts, 321 U. S. 158, 164 (1944), the Court wrote:

"If by this position appellant seeks for freedom of conscience a broader protection than for freedom of the mind, it may be doubted that any of the great liberties insured by the First Article can be given higher place than the others. All have preferred position in our basic scheme. Schneider v. State, 308 U. S. 147; Cantwell v. Connecticut, 310 U. S. 296. All are interwoven there together. Differences there are, in them and in the modes appropriate for their exercise. But they have unity in the charter's prime place because they have unity in their human sources and functionings."

APPEAL FROM THE UNITED STATES COURT OF APPEALS FOR THE ELEVENTH CIRCUIT
No. 83-812. Argued December 4, 1984-Decided June 4, 1985

Why "differences there are" instead of the customary "there are differences"? (Assuming, of course, that "there are differences" was the customary written form in 1944.)
