Personality

What personality type is Leonhard Euler? Leonhard Euler is an INTP personality type in MBTI, 5w6 - so/sp - in Enneagram, RCOEI in Big 5, LII in Socionics.

• Euler: "Logic is the foundation of the certainty of all the knowledge we acquire." >>> (Any type can rely on logic, even those that repress Thinking, but to rely on logic in the way that Euler describes is characteristic of INTPs, who seek impartial and universalized foundational principles (Ti) that often have an added solidity to them because of tertiary Si.) • Euler: "Since the fabric of the universe is most perfect, and is the work of a most wise Creator, nothing whatsoever takes place in the universe in which some relation of maximum and minimum does not appear." >>> (This is evidence of dominant Thinking with repressed Feeling in general, which tends to favor an impartial ontological standard (in this case, quantity), while at the same time denying the validity of more connotative and interpretative ways of evaluation. In addition, the appeal to foundational perfection is a very Ti way of interpreting the world, wherein the universalized subjective idea is paramount.) • Euler: "The kind of knowledge which is supported only by observations and is not yet proved must be carefully distinguished from the truth; it is gained by induction, as we usually say. Yet we have seen cases in which mere induction led to error. Therefore, we should take great care not to accept as true such properties of the numbers which we have discovered by observation and which are supported by induction alone. Indeed, we should use such discovery as an opportunity to investigate more exactly the properties discovered and to prove or disprove them; in both cases we may learn something useful." >>> (Doubting the validity of the immediate external perspective as a legitimate source of knowledge is characteristic of the overzealous nature of tertiary Si in IN-Ps, which tends to crowd out any awareness of the opposite attitude's perspective ("Se blindness," is the common term for this). We see this quality in René Descartes as well. The need to push beyond an initial observation and come to a definitive conclusion about it is evidence for a dominant judging function. On the whole, both Thinking types use induction and deduction, but Te dominant types tend to trust induction more than Ti types because of its expediency.) • from Euler's Wikipedia entry: "In 1988, readers of the Mathematical Intelligencer voted [Euler's identity] "the Most Beautiful Mathematical Formula Ever". In total, Euler was responsible for three of the top five formulae in that poll." >>> (Ti doesn't merely seek a formula that 'works'. It seeks the most elegant version of the formula, i.e. the one that expresses the 'most truth' using the least amount of notation. There is an aesthetic element that creeps into play here that we usually don't see with Te, whose focus is usually on pure function. Einstein, for example, said that "Pure mathematics is, in its way, the poetry of logical ideas.")
