“It is willingly granted that by cultivation the origination of new varieties is favored, and that by man's labor many varieties are acquired which, under natural conditions, would be lost; but nothing justifies the assumption that the tendency to formation of varieties is so extraordinarily increased that the species speedily lose all stability, and their offspring diverge into an endless series of extremely variable forms. Were the change in the conditions the sole cause of variability we might expect that those cultivated plants which are grown for centuries under almost identical conditions would again attain constancy.”

“The victory of Christ gained us the kingdom of grace, the kingdom of heaven. Easter is the sky banner flag, the flag of eternity, the victory blowing over the gates of the Holy City of Jerusalem.”

“Gärtner by the results of these transformation experiments, was led to oppose the opinion of those naturalists who dispute the stability of plant species and believe in a continuous evolution of vegetation. He perceives in the complete transformation of one species into another an indubitable proof that species are fixed within limits beyond which they cannot change.”

“Jesus let the infidels and Jews aside, he appeared only to the chosen apostles, he was concerned only with the faithful believers. To these he taught, rebuked, and sanctified, in order to perfect them to perfect the saints. This not only made sin and death be taken away from us, but by the resurrection of the Son of God grace was also obtained.”

“I am inclined to regard the separation of parental traits in the progeny of hybrids in Pisum as complete and thus permanent. The progeny of hybrids carries one or the other of the parental traits, or the hybrid form of the two; I have never observed gradual transitions between the parental traits or a progressive approach towards one of them. The course of development consists simply in this; that in each generation the two parental traits appear, separated and unchanged, and there is nothing to indicate that one of them has either inherited or taken over anything from the other”
