"Justified true belief is a definition of knowledge that is most frequently credited to Plato and his dialogues. The concept of justified true belief states that in order to know that a given proposition is true, one must not only believe the relevant true proposition, but one must also have justification for doing so. In more formal terms, a subject S knows that a proposition P is true if and only if:
(1) P is true,
(2) S believes that P is true, and
(3) S is justified in believing that P is true" [Justified true belief. Wikipedia]

"Sustainable development is an organizing principle for human life on a finite planet. It posits a desirable future state for human societies in which living conditions and resource-use meet human needs without undermining the sustainability of natural systems and the environment, so that future generations may also have their needs met.
Sustainable development ties together concern for the carrying capacity of natural systems with the social and economic challenges faced by humanity. As early as the 1970s, 'sustainability' was employed to describe an economy "in equilibrium with basic ecological support systems." Scientists in many fields have highlighted The Limits to Growth, and economists have presented alternatives, for example a 'steady state economy', to address concerns over the impacts of expanding human development on the planet."

In maths logic Venn diagram is "a diagram in which mathematical sets or terms of a categorial statement are represented by overlapping circles within a boundary representing the universal set, so that all possible combinations of the relevant properties are represented by the various distinct areas in the diagram".
