Nothing comes to pass in nature, which can be set down to a flaw therein; for nature is always the same and everywhere one and thesame in her efficiency and power of action; that is, nature's laws and ordinances whereby all things come to pass and change from one form to another, are everywhere and always; so that there should be one and the same method of understanding the nature of all things whatsoever, namely, through nature's universal laws and rules. - Baruch Spinoza
