Excerpt from The Origin of Species Charles Darwin
11 must here introduce a short digression. In the case of animals and plants with separated sexes, it is of course obvious that
two individuals must always unite for each birth; but in the case of hermaphrodites this is far from obvious. Nevertheless there is
reason to believe that with all hermaphrodites, two individuals, either occasionally, or habitually, concur for the reproduction of
their kind. This view was long ago doubtfully suggested by Sprengel, Knight, and Kolreuter. We shall presently see its
importance; but I must here treat the subject with extreme brevity, though I have the materials prepared for an ample
discussion

Asap plz which sentence from this excerpt of jefferson davis’s inaugural address indicates that secession was the confederacy’s way of reclaiming its legal powers? an agricultural people, whose chief interest is the export of a commodity required in every manufacturing country, our true policy is peace, and the freest trade which our necessities will permit . . there can be but little rivalry between ours and any manufacturing or navigating community, such as the northeastern states of the american union. it must follow, therefore, that a mutual interest would invite good will and kind offices. if, however, passion or the lust of dominion should cloud the judgment or inflame the ambition of those states, we must prepare to meet the emergency and to maintain, by the final arbitrament of the sword, the position which we have assumed among the nations of the earth. we have entered upon the career of independence, and it must be inflexibly pursued. through many years of controversy with our late associates, the northern states, we have vainly endeavored to secure tranquillity, and to obtain respect for the rights to which we were entitled. as a necessity, not a choice, we have resorted to the remedy of separation; and henceforth our energies must be directed to the conduct of our own affairs, and the perpetuity of the confederacy which we have formed. if a just perception of mutual interest shall permit us peaceably to pursue our separate political career, my most earnest desire will have been fulfilled. but, if this be denied to us, and the integrity of our territory and jurisdiction be assailed, it will but remain for us, with firm resolve, to appeal to arms and invoke the blessings of providence on a just cause . .
