Man was destined for society. His morality therefore was to be formed to this object. He was endowed with a sense of right and wrong merely relative to this. This sense is as much a part of his nature as the sense of hearing, seeing, feeling; it is the true foundation of morality... The moral sense, or conscience, is as much a part of man as his leg or arm. It is given to all human beings in a stronger or weaker degree, as force of members is given them in a greater or less degree. It may be strengthened by exercise, as may any particular limb of the body.
Thomas JeffersonDuring the course of administration, and in order to disturb it, the artillery of the press has been levelled against us, charged with whatsoever its licentiousness could devise or dare. These abuses of an institution so important to freedom and science are deeply to be regretted, inasmuch as they tend to lessen its usefulness and to sap its safety.
Thomas JeffersonNothing but free argument, raillery and even ridicule will preserve the purity of religion.
