Please keep in mind this is an excerpt from an article and should give you a little more information on what you asked:
ConservatismSimplified Definition:
An ideal conservative believes in the importance of the individual person, including the fetus, and the family structure and that it is the responsibility for the individuals within each family to do as much as they can for themselves before asking for assistance. When assistance is needed the progressive route taken is community, city, county, state and federal, in that order, with the federal government the avenue of last resort. A conservative believes in the least government possible.
Liberalism - from the foregoing we find that this term conveys the following:
Government should correct economic deficiencies caused by an unregulated free market economy.
Government should provide social welfare.
It is right for government to impose progressive income taxation.
Government should impose a minimum wage.
The social security system should remain a system where those working support those who are receiving social security payments.
Government should support only public education paid for by taxpayers even though some object to some of the subject matter and the manner in which it is taught.
Government should impose stringent safety and health regulations.
Government should impose stringent consumer protection and environmental preservation laws.
Simplified definition:
An ideal liberal takes the completely opposite position to an ideal conservative, vying for a socialistic form of government working from the top down wherein the freedom of the individual is compromised for the anticipated good of the collective group.
Please note that these definitions do not include side issues such as abortion, gun control, immigration, campaign reform etc. Conservatives and liberals may have similar positions without compromising their respective ideal ideology.
In summation, the fundamental difference between a liberal and conservative is whether an individual is allowed the freedom, with attendant responsibility, to freely function in society - or - whether an individualĀ“s interests are subservient to the collective interest of the members of society. One must either be one or the other because once the collective interest takes precedence an individualĀ“s freedom is compromised, then it just becomes a matter of degree as to the extent. A liberal who compromises his ideal ideology may consider himself a moderate liberal but is still a liberal. It is difficult for a conservative to be a moderate conservative because any compromise involves usurping individual freedom and attendant personal responsibility and this would then tend to define him as a moderate liberal.
