The Four Cardinal Virtues of Freemasonry are Temperance, Fortitude, Prudence and Justice.
Temperance is that due restraint against the affections and passions which renders the body tame and governable and frees the mind from the allurements of vice. This virtue should be your constant practice as you are thereby taught to avoid excess or the contracting of any licentious or vicious habits, the indulgence of which might lead you to disclose some of the valuable secrets which you have promised to conceal and never reveal…
Fortitude is that noble and steady purpose of the mind whereby we are enabled to undergo any pain, peril, or danger, when prudentially deemed expedient. This virtue is equally distant from rashness and cowardice, and, like the former virtue, should be deeply impressed upon your mind, as a safeguard or security against any illegal attempt which may be made, by force or otherwise, to extort from you any of those valuable secrets with which you have been so solemnly entrusted…
Prudence teaches us to regulate our lives and actions agreeably to the dictates of reason, and is that faculty by which we wisely judge and prudentially determine on all things relative to our present, as well as our future happiness. This virtue should be your peculiar characteristic, not only for the government of your conduct while in the Lodge, but also when abroad in the world. You should be particularly careful, in all strange and mixed companies, never to let fall the least sign, token, or word whereby the secrets of Freemasonry might be unlawfully obtained…
Justice is that standard or boundary of right which enables us to render unto every man his just due, without distinction. This virtue is not only consistent with divine and human laws, but is the very cement and support of civil society; and, as justice in a great measure constitutes the really good man, so should it be your invariable practice never to deviate from the minutest principles…

As a Master Mason, reflect deeply upon the virtues, and put them into practice daily. Shine as a beacon of virtue to your peers and community and many will be inspired to emulate you.
