Abstract
We have found the most general solution for the Bianchi type-I equations in the Brans-Dicke theory (BDT) for the vacuum case. It is shown that forw > 500 the Universe will become isotropic for any amount of initial anisotropy, secondly it is shown that in the extended inflation scenario, the BDT-scalar field φ can avoid the inflation in one direction,R 3. In the other scale factorsR 1 andR 2 there is inflationary expansion.
