?My reflection, when I first made myself master of the central idea of the 'Origin' [Charles Darwin's Origin of Species], was, 'How extremely stupid not to have thought of that!?
?Nature does make jumps now and then, and a recognition of the fact is of no small importance in disposing of many minor objections to the doctrine of transmutation.? ?Thomas Henry Huxley
?My good and kind agent for the propagation of the Gospel?i.e. the devil?s Gospel.? -Charles Darwin
"The student of Nature wonders the more and is astonished the less, the more conversant he becomes with her operations; but of all the perennial miracles she offers to his inspection, perhaps the most worthy of admiration is the development of a plant or of an animal from its embryo. Examine the recently laid egg of some common animal, such as a salamander or newt. It is a minute spheroid in which the best microscope will reveal nothing but a structureless sac, enclosing a glairy fluid, holding granules in suspension. But strange possibilities lie dormant in that semi-fluid globule. Let a moderate supply of warmth reach its watery cradle, and the plastic matter undergoes changes so rapid, yet so steady and purposelike in their succession, that one can only compare them to those operated by a skilled modeller upon a formless lump of clay. As with an invisible trowel, the mass is divided and subdivided into smaller and smaller portions, until it is reduced to an aggregation of granules not too large to build withal the finest fabrics of the nascent organism. And, then, it is as if a delicate finger traced out the line to be occupied by the spinal column, and moulded the contour of the body; pinching up the head at one end, the tail at the other, and fashioning flank and limb into due salamandrine proportions, in so artistic a way, that, after watching the process hour by hour, one is almost involuntarily possessed by the notion, that some more subtle aid to vision than an achromatic, would show the hidden artist, with his plan before him, striving with skilful manipulation to perfect his work."
L'autore: English biologist Thomas Henry Huxley (1825-95) was the foremost advocate of Darwin's theory of evolution, which he was "prepared to go to the stake" to defend. The controversies surrounding Darwin in the Victorian age became a vehicle for Huxley to gain power in intellectual, institutional, and political arenas.
