Evolution: Its nature, its evidence, and its relation to religious thought

Again: Every reader of the first edition must have remarked that there are many fundamental religious questions which I have not touched at all in Part III. I had avoided these because my own mind was not yet fully clear. I regarded what I then wrote as only a little leaven in...

Chapters

32. CHAPTER IX.

As already stated, page 40, the use of the method of experiment in the field of biology is, unfortunately, very limited. Nevertheless, it is already beginning to be used more an...

31. CHAPTER VIII.

It is well known that the kinds of organisms found in widely-separated countries differ more or less conspicuously. The traveler in Australia or in Africa finds all, the travele...

22. CHAPTER I.

=A Type of Evolution.=--Every one is familiar with the main facts connected with the development of an egg. We all know that it begins as a microscopic germ-cell, then grows int...

36. CHAPTER IV.

There are two widely distinct views concerning the relation of man to Nature; the one as old as the history of human thought, the other only now urged upon us by modern science....

30. CHAPTER VII.

It is a curious and most significant fact that the successive stages of the development of the _individual_ in the higher forms of any group (ontogenic series) resemble the stag...

41. CHAPTER IX.

The problem of evil has tasked the power and baffled the skill of the greatest thinkers in every age. It would be folly in me to imagine that I can solve it. Its complete soluti...

23. CHAPTER II.

In order to clear up the conception of evolution, it is necessary to give a brief history of the idea, and especially to explain the relation of Louis Agassiz to that theory. Th...

26. CHAPTER III.

We have given in the previous chapter six factors of evolution--viz.: 1. _Pressure of the environment._ 2. _Use and disuse of parts._ 3. _Natural selection._ 4. _Sexual selectio...

28. CHAPTER V.

The proposition to be established here is, that all vertebrates have not only a common general plan of structure, but an essential identity even in detail, although this identit...

38. CHAPTER VI.

It will be observed that the views presented in the last three chapters are closely connected with one another, and all conditioned on the “Relation of God to Nature,” urged in...

24. CHAPTER I.

Let us again remind the reader that evolution means, first of all, _continuity_. The law of evolution, although it doubtless means much more, means, first of all, a law of conti...

34. CHAPTER II.

It is seen in the sketch given in the previous chapter that, after every struggle between theology and science, there has been a readjustment of some beliefs, a giving up of som...

25. CHAPTER II.

It will be seen from the preceding chapter that we regard the law of evolution in its wider sense, viz., the derivative origin of all forms, organic or other, as axiomatic, and...

29. CHAPTER VI.

We have taken the vertebrate skeleton first, only because this department is most familiar. But in reality, the most beautiful illustrations of essential identity of structure i...

27. CHAPTER IV.

=Analogy and Homology.=--In biology those organs or parts in different animals are said to be _analogous_ which, however different their origin, have a general similarity of for...

33. CHAPTER I.

From what has preceded, the reader will perceive that we regard the law of evolution as thoroughly established. In its most general sense, i. e., as a law of continuity, it is a...

39. CHAPTER VII.

The doctrine of the Divine immanency carries with it the solution of many vexed questions. In fact, in its light these questions simply pass out of view as no longer having any...

35. CHAPTER III.

We have already said that evolution does not differ essentially from other laws of Nature in its bearing on religious belief. It only reiterates and enforces with additional emp...

40. CHAPTER VIII.

What think ye of Christ? This is indeed in many ways a test-question, and we ought frankly to meet it. I have feared heretofore to touch this question. I now only throw out some...

37. CHAPTER V.

In the two preceding chapters we have discussed the relation of God to Nature and of man to Nature. There is still another relation, if possible, of still more vital importance...
