Usually, a liberal is considered to be with a “free thought” trying out new things and conservatives the exact opposite. But a little contemplation will tell us that these two words are indeed relative. The moral, social and political positioning one takes can be different depending on who is looking at you and from where. There is the proverbial LEFT POLE and the RIGHT POLE. Just like any direction away from the North pole is South, any opinion away from the Left pole is right inclined and any opinion away from Right pole is left inclined. Steven Pinker makes a good point about these relative positions:

The meanings of the words are of no help. Marxists in the Soviet Union and its aftermath were called conservatives; Reagan and Thatcher were called revolutionaries. Liberals are liberal about sexual behavior but not about business practices; conservatives want to conserve communities and traditions but they also favor the free market economy that subverts them. People who call themselves “classical liberals” are likely to be called “conservatives” by adherents of the version of leftism known as political correctness.
Nor can most contemporary liberals and conservatives articulate the cores of their belief systems. Liberals think that conservatives are just amoral plutocrats, and conservatives think that if you are not a liberal before you are twenty you have no heart but if you are a liberal after you are twenty you have no brain (attributed variously to Georges Clemenceau, Dean Inge, Benjamin Disraeli, and Maurice Maeterlinck). Strategic alliances-such as the religious fundamentalists and free-market technocrats on the right, or the identity politicians and civil libertarians on the left-may frustrate the search for any intellectual common denominator. Everyday political debates, such as whether tax rates should be exactly what they are or a few points higher or lower, are just as uninformative.
