The Filosofia Regular family is designed for text applications. It is somewhat rugged with reduced contrast to withstand the reduction to text sizes. The Filosofia Grand family is intended for display applications and is therefore more delicate and refined. An additional variant, included in the Grand package, is a Unicase version which uses a single height for characters that are otherwise separated into upper and lower case. This is similar to Bradbury Thompson’s Alphabet 26, except that Thompson’s goal was to create a text alphabet free of such redundancies as the two different forms which represent the character “a” or “A”, whereas Filosofia Unicase does have stylistic variants to provide flexibility for headline use.
