This is a mistaken view: the man who guesses the secret of Freemasonry, and to know it you must guess it, reaches that point only through long attendance in the lodges, through deep thinking, comparison, and deduction.

He would not trust that secret to his best friend in Freemasonry, because he is aware that if his friend has not found it out, he could not make any use of it after it had been whispered in his ear.

No, he keeps his peace, and the secret remains a secret.
Everything done in a lodge must be secret; but those who have unscrupulously revealed what is done in the lodge, have been unable to reveal that which is essential; they had no knowledge of it, and had they known it, they certainly would not have unveiled the mystery of the ceremonies.
The impression felt in our days by the non-initiated is of the same nature as that felt in former times by those who were not initiated in the mysteries enacted at Eleusis in honour of Ceres.

But the mysteries of Eleusis interested the whole of Greece, and whoever had attained some eminence in the society of those days had an ardent wish to take a part in those mysterious ceremonies, while Freemasonry, in the midst of many men of the highest merit, reckons a crowd of scoundrels whom no society ought to acknowledge, because they are the refuse of mankind as far as morality is concerned.
In the mysteries of Ceres, an inscrutable silence was long kept, owing to the veneration in which they were held.

Besides, what was there in them that could be revealed?
The three words which the hierophant said to the initiated?
But what would that revelation have come to?
Only to dishonour the indiscreet initiate, for they were barbarous words unknown to the vulgar.
