The statement is false. The speaker actually believes that good fences make good neighbors in the poem "Mending Wall" by Robert Frost. To determine this, you can analyze the lines within the poem itself. In the poem, the speaker questions the need for a wall and suggests that it is unnecessary. However, the neighbor repeatedly states the old saying, "Good fences make good neighbors," emphasizing his belief in the importance of maintaining the wall.
