Here is the prime condition of success: Concentrate your energy, thought and capital exclusively upon the business in which you are engaged. Having begun on one line, resolve to fight it out on that line, to lead in it, adopt every improvement, have the best machinery, and know the most about it.

John Ray

John Ray (November 29, 1627 - January 17, 1705) was an English naturalist, sometimes referred to as the father of English natural history. Until 1670, he wrote his name as John Wray although no one knows why. [ citation needed ]

He published important works on plants, animals, and natural theology. His classification of plants in his Historia Plantarum , was an important step towards modern taxonomy. Ray rejected the system of dichotomous division by which species were classified according to a pre-conceived, either/or type system, and instead classified plants according to similarities and differences that emerged from observation. Thus he advanced scientific empiricism against the deductive rationalism of the scholastics.
