Synthesized answer
The provided passages do not explicitly list the evidence the author provides in "The Problems of Philosophy." However, the author states their intention to focus on problems where they could "say something positive and constructive" rather than offering "merely negative criticism" [1]. This suggests the author will present arguments and reasoning to support their philosophical positions.
The passages indicate that the author prioritizes "theory of knowledge" and will address some topics "very briefly, if at all" [1]. This implies that the evidence presented will likely be related to epistemology. The specific types of evidence, such as empirical observations, logical deductions, or thought experiments, are not detailed in the provided text.

From the book
Title: The Problems of Philosophy by Bertrand Russell Description: In the following pages I have confined myself in the main to those problems of philosophy in regard to which I thought it possible to say something positive and constructive, since merely negative criticism seemed out of place. For this reason, theory of knowledge occupies a larger space than metaphysics in the present volume, and some topics much discussed by philosophers are treated very briefly, if at all.
