The following questions refer to the excerpt below.
"...Your letter alludes to many topics of interest.First of all this 'Woman's Rights Convention,' held at Worcester,Mass.I have read through all the proceedings carefully.They show great energy,much right feeling,but not,to my judgment,a great amount of strong,clear thought.This last,of course,one ought not to expect in the beginning;but in my own mind I have settled it as a society to respect,to feel sympathy for,to help incidentally,but not-for me-to work with body and soul.I cannot sympathize fully with an anti-man movement.I have had too much kindness,aid,and just recognition from men to make such attitude of women otherwise than painful;and I think the true end of freedom may be gained better in another way… But I feel a little perplexed by the main object of the Convention -- Woman's Rights.The great object of education has nothing to do with a woman's rights,or man's rights,but with the development of the human soul and body.But let me know how you mean to treat the subject,and I will render you what aid I can ....My head is full of the idea of organisation,but not the organisation of women in opposition to men.I have been lately meditating constantly on this idea,and seeking some principle of organisation which should be a constantly growing one,until it became adequate to meet the wants of the time ..."
Dr.Elizabeth Blackwell,December 24,1850
