Now let us ask--what was it that originally drove Charles to books of Casuistry? It was the deep shock which he received, both in his affections and his conscience, from the death of Lord Strafford. Every body had then told him, even those who felt how much the law must be outraged to obtain a conviction of Lord Strafford, how many principles of justice must be shaken, and how sadly the royal word must suffer in its sanctity,--yet all had told him that it was expedient to sacrifice that nobleman. One man ought not to stand between the king and his alienated people. It was good for the common welfare that Lord Strafford should die. Charles was unconvinced. He was sure of the injustice; and perhaps he doubted even of the expedience. But his very virtues were armed against his peace. In all parts of his life self-distrust and diffidence had marked his character. What was he, a single person, to resist so many wise counsellors, and what in a representative sense was the nation ranged on the other side? He yielded: and it is not too much to say that he never had a happy day afterwards. The stirring period of his life succeeded--the period of war, camps, treaties. Much time was not allowed him for meditation. But there is abundant proof that such time as he had, always pointed his thoughts backwards to the afflicting case of Lord Stratford. This he often spoke of as the great blot--the ineffaceable transgression of his life. For this he mourned in penitential words yet on record. To this he traced back the calamity of his latter life. Lord Stratford's memorable words--'Put not your trust in princes, nor in the sons of princes,'--rang for ever in his ear. Lord Stafford's blood lay like a curse upon his throne. Now, by what a pointed answer, drawn from this one case, might Charles have replied to the enemies we have noticed--to those, like so many historians since his day, who taxed him with studying Casuistry for the purposes of intrigue--to those, like Milton and Henderson, who taxed him with exercising his private conscience on public questions. 'I had studied no books of Casuistry,' he might have replied, 'when I made the sole capital blunder in a case of conscience, which the review of my life can show. 'I did not insist on my private conscience; woe is me that I did not: I yielded to what was called the public conscience in that one case which has proved the affliction of my life, and which, perhaps, it was that wrecked the national peace.'
