Science = Materialism

With Idealism humans could not have the real science.
Freethought: beliefs should be based on reason.
Should not be affected by authority, tradition or dogma.

It is a rejection of Faith which leads to dogma.

A real materialist must face against destiny. Fight against the belief without reason, against any influence to be controlled.

Science is needed. Must work scientifically. It means that to succeed, materialism is required.
