Reason and free inquiry are the only effective agents against error. Give a loose to them, they will support the true religion by bringing every false one to their tribunal, to the test of their investigation. They are the natural enemies of error and error only.

Had not free inquiry been indulged at the era of the Reformation, the corruption of Christianity could not have been purged away.
Thomas JeffersonThe relations which exist between man and his Maker, and the duties resulting from those relations, are the most interesting and important to every human being and the most incumbent on his study and investigation.
Thomas JeffersonA man has a right to use a saw, an axe, a plane, separately; may he not combine their uses on the same piece of wood? He has a right to use his knife to cut his meat, a fork to hold it; may a patentee take from him the right to combine their use on the same subject? Such a law, instead of enlarging our conveniences, as was intended, would most fearfully abridge them, and crowd us by monopolies out of the use of the things we have.
Thomas JeffersonWe do, then, most solemnly before God and the world declare that regardless of every consequence, at the risk of every distress, the arms we have been compelled to assume we will use with perseverance, exerting to their utmost energies all those powers which our Creator hath given us to preserve that liberty which he committed to us in sacred deposit and to protect from every hostile hand our lives and our properties.
Thomas Jefferson
