Felicity is a continual progress of the desire from one object to another, the attaining of the former being still but the way to the latter.
Thomas HobbesThe end of knowledge is power ... the scope of all speculation is the performing of some action or thing to be done.
Thomas HobbesThe cause of Sense, is the External Body, or Object, which presseth the organ proper to each Sense, either immediately, as in theTaste and Touch; or mediately, as in Seeing, Hearing, and Smelling: which pressure, by the mediation of Nerves, and other strings, and membranes of the body, continued inwards to the Brain, and Heart, causeth there a resistance, or counter- pressure, or endeavor of the heart, to deliver it self: which endeavor because Outward, seemeth to be some matter without.
Thomas Hobbes
