But to him this adaptation was easier than to many Friends. He was a scholar and man of letters by habit and instinct. It was a necessity of his nature that he should see clearly the whole scope and logical inferences of his principles. His intellectual fearlessness is wonderful. His learning was not idle lumber in his mind. It bore some important relation, either of agreement or of antagonism, to his views, and to the arguments of his assailants. It was either light in which he could rejoice, or shadow which revealed some obstruction to the light, and threw out the light into bolder contrast. So learning had to him a real use and value; it was not counters but coins and the world of books was to him a very real world. The progress of Quakerism in the neighborhood of Aberdeen, filled the hearts of many with malice that would stoop to any meanness, and carry out any iniquity. They actually demolished the walls of the Friends' burying-ground, and removed the dead bodies elsewhere; and after some subsequent interments, they kept up the practice, until stopped by the king's Council. But it was not in Aberdeen but at Montrose that Robert Barclay first suffered imprisonment for conscience sake. It happened thus. Most of the Quakers at Kinnaber near Montrose, after being in prison for two months for the high crime of meeting together to worship God, had been released by the king's Council at the instance of John Swintoune. That gentleman and Robert Barclay sympathisingly determined to join them in their first public service, and did so. As the company was dispersing, the constables arrived, and arrested William Napier, at whose house the meeting was held, and carried him before the magistrates. Swintoune and Barclay went with him, and insisted on seeing the magistrates, and reasoning with them. On this they too were committed to prison, the ground alleged being that they had been present at the meeting. But they do not seem to have been many days in prison before the king's Council again interfered and liberated them. Whilst in prison they addressed a spirited remonstrance to the magistrates, boldly and vigorously telling them the unvarnished truth about their conduct, and appealing to them to act more righteously in future. Thus they were not behind their English brethren in the vigour with which they fought the battle of religious liberty.
