There is something fascinating about science. One gets such wholesale returns of conjecture out of such a trifling investment of fact.
For every living creature that succeeds in getting a footing in life there are thousands or millions that perish. There is an enormous random scattering for every seed that comes to life. This does not remind us of intelligent human design. "If a man in order to shoot a hare, were to discharge thousands of guns on a great moor in all possible directions; if in order to get into a locked room, he were to buy ten thousand casual keys, and try them all; if, in order to have a house, he were to build a town, and leave all the other houses to wind and weather - assuredly no one would call such proceedings purposeful and still less would anyone conjecture behind these proceedings a higher wisdom, unrevealed reasons, and superior prudence."
Can you define "plan" as "a loose sequence of manifestly inadequate observations and conjectures, held together by panic, indecision, and ignorance"? If so, it was a very good plan.
To be willing to die for an idea is to set a rather high price on conjecture.
The mind revels in conjecture. Where information is lacking, it will gladly fill in the gaps.
