**Introduction.**

Occam's razor, also written as Ockham's razor, or law of parsimony, is a problem-solving principle attributed to William of Ockham (c. 1287–1347), who was an English Franciscan friar, scholastic philosopher and theologian.

The principle can be interpreted as: 'stating among competing hypotheses, the one with the fewest assumptions should be selected'.

According to Ockham, 'simpler theories are preferable to more complex ones'.

**Discriminating Wisdom.**

Discriminating Wisdom in Buddhism is the wisdom that allows to see things (for example: scientific assumptions) clearly, 'as they are', in a separation as well as a part of larger whole, nondually.

**Uses in Science.**

Assumptions can be complex or simple. Complex assumptions consist of multiple assumptions, either complex or simple, or of a mix of these.

Complex assumptions can be reduced to a set of simpler partial assumptions, then can be looked with a discriminating wisdom, modelled and analyzed to see if any of the partial assumptions can be removed for a simpler model.

Simpler models often do not restrict us so much, allow for more options based on a fewer of the assumptions.

**An Example.**

To have a square precisely defined, we need to provide either:

1. A vector/turn definition.

- a vector with a direction,

- a turn at the vector's end.

2. A two straight lines with a point definition.

- a straight line,

- a second straight line, parallel but not overlapping first line,

- a point.

This can be reduced using the 'Ockham's razor' and the 'Discriminating Wisdom' to a basic sets of simple partial assumptions:

[Discriminating wisdom is used to reduce complex assumptions into a set of simpler partial assumptions, then to analyze].

[Ockham's razor is used to remove redundant information, such as the requirement for a point between two lines to be placed exactly in the middle of a square - a perpendicular straight line can be placed through this point, then this point can be moved along the perpendicural straight line into the midst of the square].

Let's not prune too much or too little of the neccessary premises information, however. We need all of required premises to do attribution in a sane way - to jump into a conclusion in a sane way.

1. A vector/turn definition.

- we know a starting coordinates of a vector,

- we know the end coordinates of a vector,

- the starting and end points of a vector are not overlapping,

- we know a turn at the end of a vector: either to left or to right.

2. A two straight lines with a point definition.

- we know an equation of the first straight line,

- we know an equation of the second straight line,

- lines defined by equations are parallel,

- lines defined by equations are not overlapping,

- we know coordinates of a point.

By looking at both definitions, we can see that definition with a vector/turn requires fewer assumptions about our knowledge of a square than a definition with two lines and a point.

Our first definition is simpler and therefore superior by principles of the Ockham's razor theory.
