The value of science to a republican people, the security it gives to liberty by enlightening the minds of its citizens, the protection it affords against foreign power, the virtue it inculcates, the just emulation of the distinction it confers on nations foremost in it; in short, its identification with power, morals, order and happiness (which merits to it premiums of encouragement rather than repressive taxes), are considerations [that should] always [be] present and [bear] with their just weight.
Thomas JeffersonWhen virtue is banished, ambition invades the minds of those who are disposed to receive it, and avarice possesses the whole community. The objects of their desires are changed; what they were fond of before has become indifferent; they were free while under the restraint of laws, but they would fain now be free to act against law.
Thomas JeffersonThe proscribing any citizen as unworthy the public confidence by laying upon him an incapacity of being called to offices of trust and emolument unless he profess or renounce this or that religious opinion is depriving him injuriously of those privileges and advantages to which, in common with his fellow citizens, he has a natural right.
Thomas JeffersonI see,... and with the deepest affliction, the rapid strides with which the federal branch of our government is advancing towards the usurpation of all the rights reserved to the States, and the consolidation in itself of all powers, foreign and domestic; and that, too, by constructions which, if legitimate, leave no limits to their power... It is but too evident that the three ruling branches of [the Federal government] are in combination to strip their colleagues, the State authorities, of the powers reserved by them, and to exercise themselves all functions foreign and domestic.
Thomas JeffersonTo compel a man to furnish contributions of money for the propagation of opinions which he disbelieves and abhors is sinful and tyrannical...A wise and frugal government...shall not take from the mouth of labor the bread it has earned...Congress has not unlimited powers to provide for the general welfare but only those specifically enumerated...Would it not be better to simplify the system of taxation rather than to spread it over such a variety of subjects and pass through so many new hands?
