Captain Wilson then entered into a detail of the duties and rank of every person on board of the ship, pointing out to Jack, that where discipline was required, it was impossible, when duty was carried on, that more than one could command; and that that one was the captain, who represented the king in person, who represented the country; and that, as the orders were transmitted from the captain through the lieutenant, and from the lieutenant to the midshipmen, who, in their turn, communicated them to the whole ship's company, in fact, it was the captain alone who gave the orders, and that everyone was equally obliged to obey.

Indeed, as the captain himself had to obey the orders of his superiors, the Admiral and the Admiralty; all on board might be said to be equally obliged to obey.
Captain Wilson laid a strong emphasis on the word equally, as he cautiously administered his first dose; indeed, in the whole of his address, he made use of special pleading, which would have done credit to the bar; for at the same time that he was explaining to Jack that he was entering a service in which equality could never for a moment exist, if the service was to exist, he contrived to show that all the grades were levelled, by all being equally bound to do their duty to their country, and that, in fact, whether a seaman obeyed his orders, or he obeyed the orders of his superior officer, they were in reality only obeying the orders of the country, which were administered through their channels.
Jack did not altogether dislike this view of the subject, and the captain took care not to dwell too long upon it.

He then entered upon other details, which he was aware would be more agreeable to Jack.

He pointed out that the articles of war were the rules by which the service was to be guided, and that everybody, from the captain to the least boy in the ship, was equally bound to adhere to them that a certain allowance of provisions and wine were allowed to each person on board, and that this allowance was the same to all; the same to the captain as to the boy; the same in quantity as in quality; everyone equally entitled to his allowance;--that, although there were, of necessity, various grades necessary in the service, and the captain's orders were obliged to be passed and obeyed by all, yet still, whatever was the grade of the officer, they were equally considered as gentlemen.

In short, Captain Wilson, who told the truth, and nothing but the truth, without telling the whole truth, actually made Jack fancy that he had at last found out that equality he had been seeking for in vain on shore, when, at last, he recollected the language used by Mr Sawbridge the evening before, and asked the captain why that personage had so conducted himself.
