The conservative account on knowledge is based on the premise that human beings acquire knowledge about reality with aid of the five senses in a process known as sensory perception. Major proponents of this epistemological account included John Locke, David Hume, Stuart Mills and Thomas Hobbes among others. These scholars held that the mind is tabula rasa – in an empty state at birth therefore, at conception, human beings possess no knowledge a priori.
The process of attaining knowledge begins after conception when the senses begin to perceive reality through smelling, hearing, seeing, feeling and tasting aided by the respective organs. The sensory organs transmit reality to the brain, which in turn represents it in thoughts through cognition. Once the brain establishes a logical consistency between the objective reality and the notions and ideas, it is said to acquire true knowledge (Mueller, 1997).
