Why, If Species Have Descended From Other

I Am Aware That The Conclusions Arrived At In This Work Will Be Denounced By Some As Highly Irreligious; But He Who Denounces Them Is Bound To Show Why It Is More Irreligious To Explain The Origin Of Man As A Distinct Species By Descent From Some Lower From, Through The Laws Of Variation And Natural Selection, Than To Explain The Birth Of The Individual Through The Laws Of Ordinary Reproduction. The Birth Both Of The Species And Of The Individual Are Equally Parts Of That Grand Sequence Of Events, Which Our Minds Refuse To Accept As The Result Of Blind Chance.

The Willing Horse Is Always Overworked.

But Then With Me The Horrid Doubt Always Arises Whether The Convictions Of Man's Mind, Which Has Been Developed From The Mind Of The Lower Animals, Are Of Any Value Or At All Trustworthy. Would Any One Trust In The Convictions Of A Monkey's Mind, If There Are Any Convictions In Such A Mind?
