That it hath been the constant opinion of all ages, that the Parliament of England had an unquestionable Power to Limit, Restrain and Qualify the Succession as they pleased, and that in all Ages they have put their power in practise; and that the Historian had reason for saying, That seldom or never the third Heir in a right Descent enjoy'd the Crown of England.
What It Means
This is a placeholder explanation generated by the low-overhead model. It interprets "That it hath been the constant opinion of all ages, that the Parliament of England had an unquestionable Power to Limit, Restrain and Qualify the Succession as they pleased, and that in all Ages they have put their power in practise; and that the Historian had reason for saying, That seldom or never the third Heir in a right Descent enjoy'd the Crown of England." in the context of "A Brief History of the Succession, Collected out of the Records and the Most Authentick Historians (1680), quoted in State Tracts: Being a Collection of Several Treatises Relating to the Government. Privately Printed in the Reign of K. Charles II. (1693), p. 397" to mean that wisdom is timeless.
