The pragmatismo taken in general lines? how it was placed by Richard Rorty? it can be considered as antiessencialismo, that is, for the pragmatic philosophers does not have in objects an intrinsic nature, or essence, also not having an absolute truth. They try to eliminate the Metaphysical dualismos inherited of the tradition Greek: essence and accident, reality and appearance. This becomes possible to leave of side the idea of the relation between citizen-object, that the Metaphysical tradition lode constructing. For the pragmatic ones we cannot speak in essence, or in an intrinsic reality of the nature, therefore, the knowledge is on to the social necessities of the individual, and the descriptions made on the reality with the pretension to be true correspond its social necessities.

If to accept that the descriptions of the world that go to form ours knowledge is functions of our social necessities, has that to agree that the idea of the physis is only plus a description that corresponds to some social necessity.
With this we cannot affirm the existence of something as the physis or nature. Leaving of side the distinction convention-nature. We cannot precipitating in them and finding that for pragmatic the things they do not exist, and that they are only linguistic products. It is clearly that the things exist, but, what we only can speak on them are its relationary aspects with other things, with the aid is clearly of the language. It is important to understand the paper of the language that serves for the man as an instrument in the relationship with objects, to take care of its social necessities. An important point in the antiessencialismo is to eliminate the distinction between something that the X is intrinsic (X is an object here any) and something that is extrinsic.
