From Boston Commonwealth.
"The great value of the little book, 'Whence, What, Where?' by Dr. James R. Nichols, is in its suggestiveness. It is eminently provocative of thought. Its value is not to be tested by its bulk. It is full of clear thinking, and of accurate statement. Dr. Nichols is severely scientific, and, at the same time, devoutly spiritual. Its philosophy is largely that of Swedenborg, without Swedenborg's terrible diffusiveness. We have in it, concisely and clearly stated, all that the strictest scientific research warrants us in believing of man's origin, nature, and spiritual destiny. Science is shown to be not necessarily opposed to religion and to spirituality."
From Boston Christian Register.
"The book is written in a clear style, and the author's opinions are readily understood. It is refreshing to have such a work from a scientific layman, on topics which too many treat with a supercilious disdain, unbecoming both themselves and the subject."
From Boston Congregationalist.
"The topics discussed are handled with a good degree of candor, and give in a small space much interesting information and perhaps some profitable speculation."
From the Lowell Mail.
"Its truths may be received as a new revelation from which consolation and happiness may be derived by those who have been troubled with doubts and misgivings."
